what are the basic building blocks of fats?

Answers

Answer:

Fatty acids are the building blocks of the fat in our bodies and in the food we eat. During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood. Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.

What cause the slight positive (8+) and negative (8-) poles on a molecule of H20?

Answers

Answer:

In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms

Because of the water molecule's bent shape and its atoms' unequal sharing of electrons, it has partial positive (δ+) and partial negative (δ-) poles. ... A hydrogen bond occurs when molecules that have hydrogen covalently bonded to oxygen, nitrogen or fluorine interact.

Explanation:

Water is said to be a molecule made of oxygen and hydrogen atoms. There is a partial negative and positive charge at the poles of water due to hydrogen bonds, and electronegativity.

What are hydrogen bonds?

Hydrogen bonds are defined as weak chemical bonds and interactions that result from the electrostatic attraction between the electronegative atom and the proton. These bonds are formed by dipole-dipole interactions.

Oxygen atoms in the water molecule are highly electronegative whereas the hydrogen atom of the water molecules is proton donors. This results in the formation of hydrogen bonds between the oxygen atom of one molecule and the hydrogen atom of the other molecules.

The electron sharing between the hydrogen and the oxygen atom tends to be unequal resulting in bonds being slightly towards the oxygen atom due to its electronegative nature. This results in the formation of partial positive and negative charges.

Therefore, hydrogen bonding results in slight positive and negative charges.

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited

Answers

Answer:

Phenytoin and ethosuximide are drugs that slow the recovery of the sodium channel during the inactivated state.

That is to say, they prolong the inactivation state of the channel, thus generating that in this way the neuron remains in resting potential and the action potential causing the epileptic attack is not triggered.

On the other hand, these drugs, according to the bibliography of the book "Golan, 3rd Edition, Principles of Pharmacology" have a use-dependent affect capacity, this means that those sodium channels that have more activity will be more affected, in this way Not only is epileptic shock avoided, but if the same happens independently in any neuron, it will not be able to propagate the action potential to its neighboring neurons, therefore the surrounding neurons will not be stimulated and will not be fulfilled. with the sudden rapid discharges that are the most dangerous in some cases of severe epilepsy.

It is important to understand that these drugs affect the ion channels responsible for exciting neurons, that is why by inhibiting them, a constant rest of these neurons is promoted, and they are unable to generate abrupt discharges and dissemination of the electric charge. among them generating epileptic shocks.

The ions in neurons are in charge of indicating or modulating the different neuronal states, if they are inactive, open or closed, they will directly affect the membrane potential, that is, the positive or negative charge of the neuron's membrane.

Explanation:

In order to finish completing the question, these drugs are excreted through the p450 protein, that is why if this excretion system becomes saturated because another drug is consumed that is excreted in the same way, these antiepileptics will remain longer in use. blood and in the body, generating a greater effect and enhancing adverse effects on the central nervous system.

C) display each of the four key characteristics of the chordates at some point in the life cycle
D) possess a backbone in at least one life stage.

Answers

Answer:

C) display each of the four key characteristics of the chordates at some point in the life cycle

Explanation:

To be characterized as a chordate, an organism must display each of the four key characteristics of the chordates at some point in the life cycle. Therefore, the correct option is C.

To be characterized as a chordate, an organism must display four key characteristics at some point in its life cycle.

These characteristics include having a notochord (a flexible rod-like structure), a dorsal hollow nerve cord, pharyngeal slits or pouches, and a tail.

It is not necessary for all four characteristics to be present simultaneously or in both the larval and adult stages. As long as the organism exhibits these characteristics at some stage of its life, it can be classified as a chordate.

What is the appropriate protein portion for men?
A. 2 palm portions
B. 3 palm portions
C. 2 cupped handfuls
D. 3 cupped handfuls

Answers

Answer:

A is correct- 2 palm portions is an appropriate protein portion for men

Explanation:

Two palm portions is the appropriate protein portion needed for men. It is advised to consume 0.8 grams of fat per kilogram of body weight. So, option A is right.

Amino acids are the building blocks of proteins. Your body requires amino acids to create hormones and enzymes, as well as to build and repair muscles and bones. They can also be utilized as a source of energy.

For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight.

For men, 2 palm sized portions of protein is recommended in each meal. Palm is used to measure protein and handfuls is used to measure carbohydrates.

30 grams of protein are contained in one palm serving. Two palm pieces would therefore provide roughly 60 grams of protein for a man having 50-70 kilogram, which is a sufficient quantity for most guys.

Therefore, option A, 2 palm portions of protein is the appropriate protein portion for men is the correct answer.

Each enzyme can catalyze many different biochemical reactions. D. Enzymes and substrates fit together like a lock and key.

Answers

It would be answer D. because enzymes are a type of catalysts that function in living things and a substrate is a reactant that an enzyme catalyzes. An enzyme and substrate fit together perfectly like a lock and key as it catalyzes and produces a product

Enzymes are proteins that are like keys and fit into the lock called substrate to carry out the reactions. Thus, option D is accurate.

What are enzymes?

Enzymes are involved in metabolic reactions and act as catalysts by speeding up the reactions. They do not decrease the activity function of the rate of reactions in the living things.

A specific type of enzyme can catalyst only a single type of substrate and are unique for a reaction. Enzymes and substrates act as lock and key that fits together to carry out the reaction.

B. The 55 N cat has less mass than the 110 N dog.
C. The 55 N cat has the same mass as the 110 N dog when it is in

Answers

Answer:

B. The 55 N cat has less mass than the 110 N dog.

Explanation:

Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object.

In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.

Note that: if the gravitational effect is removed, the cat will contain lesser mass.
