True or False: Enzymes have an optimal or ideal pH level?

Answers

Answer 1

Answer:

All enzymes have an ideal pH value, which is called optimal pH. Under the optimum pH conditions, each enzyme showed the maximum activity. For example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. All enzymes have an optimum pH that they work best at. Its often neutral pH 7, but not always.

Answers

Answer:

I'll say B cause the Nacl ion breaks down and get surrounded by hydrogen and hydroxyl ion

Table salt dissolving in water is the example of dissociation.

What do you mean by dissociation?

Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner.

Moreover, the dissociation of water is an equilibrium reaction in which one water molecule donates its proton to another water molecule.

Salts that are soluble in water dissociate into their ions and are electrolytes. Salts that are insoluble or only slightly soluble in water form very few ions in solution and are nonelectrolytes or weak electrolytes.

Polypeptides are chains of amino acids. They can coil/fold into different shapes. Some 'R'-groups are either hydrophobic, hydrophilic, or neutral in their charge. Suppose you have a very long polypeptide, where a part of the chain is hydrophobic and another part is hydrophilic. I go ahead and drop this long polypeptide in water and it coils up. How do you think it would coil? Why? What can you infer about the proteins in our bodies regarding this situation

Answers

Answer:

The hydrophilic part of the polypeptide chain would be oriented towards the surrounding water while the hydrophobic portion would be arranged away from the water and would make the hydrophobic interior resulting in coiling of the polypeptide chain. The body proteins assume the shapes to organize their hydrophobic parts away from the watery fluid.

Explanation:

Amino acids are the monomers of proteins. Each amino acid, present in proteins, has a central carbon atom. Four functional groups are attached to the central carbon atom of amino acid. These are the carboxyl group (COOH), amino group, a hydrogen atom (H) and a side chain (called R group). Amino acids differ from each other for the side chain present in them. Based on the nature of the side chain, amino acids are hydrophobic or hydrophilic or neutral. Sidechains of some amino acids are charged and have positive or negative charges on them.

The extracellular fluid of the body is a watery medium. Blood also has liquid plasma that is 99% water. The intracellular fluid, called cytosol, is also a water-based liquid.  

The hydrophilic side chains of the amino acids interact with the watery surroundings. They can make hydrogen bonds with the water. The charged hydrophilic R groups make electrostatic interactions with the surrounding medium. The hydrophobic R groups of the amino acids tend to arrange themselves away from the watery medium. This makes the part of the polypeptide chains with hydrophobic amino acids to fold so that these R groups are oriented away from the water.

Similarly, when a long polypeptide chain is dropped in the water, the hydrophobic R groups are arranged away from the water while the hydrophilic ones are arranged towards the surface of the chain facing the water. It is done to adopt a stable shape where maximum attraction forces are established.

Answers

Answer:

We divide ER into two types because Smooth ER(SER) do not have ribosomes and Rough ER(RER) have ribosome thus former is also called Agranulated ER and Latter is called Granulated ER. SER is not involved in protein synthesis its main function is synthesis of lipids carbs steroid thus it is found in Adipose cells, interstitial cells, liver cells. RER have ribosomes so they are involved in protein synthesis so they are present in protein synthesising cells such as salivary glands and pancreas.

Why is technology important when developing scientific theories?

Why is oceanic crust younger than continental crust?

Answers

Answer:What is the best explanation for why oceanic crust is subducted by continental crust?

The continental crust is also less dense than oceanic crust, although it is considerably thicker. As a consequence of the density difference, when active margins of continental crust meet oceanic crust in subduction zones, the oceanic crust is typically subducted back into the mantle.

Explanation:Why oceanic crust is younger than Continental?

Through mantle convection, the rich minerals of the mantle may be ultimately “recycled” as they surface as crust-making lava at mid-ocean ridges and volcanoes. Largely due to subduction, oceanic crust is much, much younger than continental crustWhy is the theory of plate tectonics so important to geologists?

Answer:

Which statement correctly describes the offspring of asexual reproduction?

(Choice C)
C
They contain half of the genetic information of the parent.

(Choice D)

They develop very slowly compared to offspring of sexual reproduction.

Answers

Answer: the answer is A “They result without the fusion of gametes”

Explanation:

The statement that correctly describes the offsprings of asexual reproduction is: they result without the fusion of gametes.

ASEXUAL REPRODUCTION:Asexual reproduction is a type of reproduction that involves a single parent organism. The single parent cell gives rise to two new daughter cells by undergoing division.

As a result, the new organisms are genetically identical to one another, hence, genetic diversity is not ensured.

On the other hand, sexual reproduction involves the fusion of gametes to produce genetically different organisms.
