What are the steps in enzyme reactions?
Enzymes are proteins that catalyze chemical reactions in cells. The first step in an enzyme reaction is the binding of the substrate, the molecule that the enzyme acts on, to the active site of the enzyme.
Substrate binds to the active site of the enzyme.The enzyme-substrate complex undergoes a conformational change, bringing the substrate closer to the catalytic site.The substrate is chemically modified by the enzyme.The product(s) are released from the enzyme.The active site is a specific region on the enzyme's surface where the substrate binds. Once the substrate is bound, the enzyme may undergo a conformational change, which brings the substrate closer to the catalytic site of the enzyme. The catalytic site is the region of the enzyme where the chemical reaction takes place.
The substrate is then modified by the enzyme, resulting in the production of one or more products. Finally, the product(s) are released from the enzyme, and the enzyme is available to bind and catalyze the reaction with additional substrate molecules.

What will be the ratio of rate of diffusion between o2 and h2?
4:1 will be the ratio of rate of diffusion between [tex]O_{2}[/tex] and [tex]H_{2}[/tex].
Graham's law for the diffusion of two gases is given as:
[tex]r_{1}[/tex]/[tex]r_{2}[/tex] = [tex]\sqrt{m_{2} /m_{1} }[/tex]
Substituting the molecular weights, 32 for 2 oxygen and 2 for hydrogen, we get the ratio of rates of diffusion of [tex]H_{2}[/tex]: [tex]O_{2}[/tex] = [tex]\sqrt{32/4}[/tex] = 4:1.
What is rate of diffusion?
Diffusion in gases is the random movement of particles involved in the net movement of matter from areas of high concentration to areas of low concentration. Particles in a particular gas keep colliding with other particles. In regions of the gas with the highest particle density, the particles bounce off each other, and at the boundaries of the container they bounce more than particles in regions of lower density.

what volume of a 0.291 m solutionof naoh is requreid to reach the equivalence point in a titration against 25 ml of 0.350 m hcl
The volume of a 0.291 m solution of NaOH required to reach the equivalence point in a titration against 25 ml of a 0.350 m HCl solution is 27.50 ml.
This can be calculated using the formula VNaOH
= (25ml) × (0.350 M HCl) / (0.291 M NaOH).
The volume of a 0.291 m solution of NaOH required to reach the equivalence point in a titration against 25 ml of a 0.350 m HCl solution can be calculated using the following equation:
VNaOH = (25ml) × (0.350 M HCl) / (0.291 M NaOH) VNaOH
= 27.50 ml
Therefore, the volume of a 0.291 m solution of NaOH required to reach the equivalence point in a titration against 25 ml of a 0.350 m HCl solution is 27.50 ml.
When a titration is performed, the equivalence point is reached when the moles of the acid is equal to the moles of the base. For an acid-base titration, the equivalence point is determined by the stoichiometry of the reaction between the acid and the base. In this case, the reaction between the 0.350 m HCl and the 0.291 m NaOH is
HCl + NaOH → NaCl + H2O.
The ratio of HCl to NaOH is 1:1, which means that when the moles of HCl is equal to the moles of NaOH, the reaction is complete, and the equivalence point is reached.

What would happen if H+ ions were able to freely diffuse through the mitochondrial membrane without the need for pumps or ATP synthase?
If protons (H+) were able to freely move across the mitochondrial membrane, cellular respiration will not occur.
Mitochondria are encased in a double-membrane system made up of inner and outer mitochondrial membranes separated by an intermembranous space. The inner membrane has numerous folds (cristae) that extend into the organelle's interior. In the critical process of oxidative phosphorylation, the electrochemical proton gradient across the inner mitochondrial membrane drives ATP synthesis. This is made possible by the previously mentioned membrane-bound enzyme ATP synthase.
The electron transport chain creates a proton gradient across the inner mitochondrial membrane, causing chemiosmosis to drive ATP synthesis. The proton gradient across the cristae membrane is produced by three large membrane protein complexes of the respiratory chain in the cristae, known as complexes I (NADH/ubiquinone oxidoreductase), III (cytochrome c reductase), and IV (cytochrome c reductase) (cytochrome c oxidase).

Chloroform (CHCl3) is a derivative of CDCl3, in which the hydrogen atom ("H") is switched to the heavy hydrogen isotope deuterium ("D").
CDCl3 is used because of the following two reasons
In order to stabilise the magnetic field strength, contemporary NMR spectrometers evaluate the solvent's deuterium absorption. The deuterium receiver detects a field fluctuation through a change in the observation frequency and can adjust the field intensity accordingly because the observation frequency is field dependant.

It is also known as the freezing temperature and is the point at which the molecules of a substance slow down enough for them to form a crystalline structure. The freezing point of a substance is determined by its chemical composition and the pressure the substance is under. Generally, the freezing point decreases as the pressure of the substance increases. For most substances, the freezing point is below 0°C (32°F).

a 128 sample of oxygen gas reacts with excess nitrogen monoxide to form nitrogen dioxide gas. what volume of nitrogen dioxide will be produced at 273K and 101.3kPa (STP)
Answer:
To determine the volume of nitrogen dioxide gas produced when a sample of oxygen gas reacts with excess nitrogen monoxide, you need to know the balanced chemical equation for the reaction. Without this information, it is not possible to accurately calculate the volume of nitrogen dioxide produced.
In general, to determine the volume of a gas produced in a chemical reaction, you need to know the volume of the reactant gases and the mole ratios of the reactants and products in the balanced chemical equation. You can then use the ideal gas law to calculate the volume of the gas produced at a given temperature and pressure.
For example, if the balanced chemical equation for the reaction is:
2 O2 + 2 NO --> 2 NO2
and you know that you started with 128 g of O2, you can use the molar mass of O2 to convert the mass to moles, and then use the mole ratio from the chemical equation to determine the number of moles of NO2 produced. You can then use the ideal gas law to calculate the volume of NO2 produced at a given temperature and pressure.

A reaction mixture initially contains 4.2 mol zns and 6.8 mol o2. once the reaction has occurred as completely as possible, what amount (in moles) of the excess reactant is left?
The excess reactant left in the mixture is 0.5 mol.
What are reactants?
In a chemical reaction, reactants are the starting materials that react to form new products. Reactants are typically listed on the left side of a chemical equation, and the products are listed on the right side.
To determine the amount of excess reactant left in the reaction mixture once the reaction has occurred as completely as possible, we need to balance the chemical equation for the reaction and then use the balanced equation to calculate the amount of excess reactant.
Assuming that the reaction is:
ZnS + O2 -> ZnO + SO2
The balanced chemical equation would be:
2 ZnS + 3 O2 -> 2 ZnO + 2 SO2
Once the reaction has occurred as completely as possible, the amount of each reactant present in the reaction mixture can be calculated using the mole ratios from the balanced equation.
For example, if the amount of ZnS present in the reaction mixture is 4.2 mol, the amount of O2 present can be calculated as follows:
O2 = (4.2 mol ZnS) x (3 mol O2 / 2 mol ZnS) = 6.3 mol O2
Since the initial amount of O2 present in the reaction mixture was 6.8 mol, the excess reactant is 6.8 mol O2 - 6.3 mol O2 = 0.5 mol O2.
Therefore, the amount of excess reactant (O2) left in the reaction mixture once the reaction has occurred as completely as possible is 0.5 mol.

(CH3)2-CH-CH2-CH2-CH(OH)-CH2-CH2-COO-CH2-CH3 is formed when (CH3)2C═CHCH2COCH2CH2COOCH2CH3 is treated with H2 (2 equiv), Pd―C.
Palladium on carbon is used for catalytic hydrogenations in chemical synthesis. Examples include reductive amination, carbonyl reduction, nitro compound reduction, imine and Schiff base reduction, and debenzylation processes.
Palladium is a very selective metal for a wide range of hydrogenation reactions, including the selective reduction of a C=C double bond next to an aliphatic carbonyl. The Lindlar catalyst is a well-known example of increased palladium selectivity. Carbon atoms smash with a palladium atom, bringing them so close that chemical reactions are possible. The catalyst in "palladium-catalyzed cross coupling" is palladium. It "encourages" and "allows" individual carbon atoms to react.
