The metabolic fate of fatty acids is dependent on two enzymes, carnitine acyltransferase i and acetyl-coa carboxylase. carnitine

zvonat [6]

The correct answer is the last statement.

If the regulatory serine is mutated to alanine, then acetyl-CoA carboxylase will get activated spontaneously and will produce malonyl-CoA. The increased concentrations of malonyl-CoA will obstruct the oxidation of fatty acids by preventing the entry of fatty acids into the mitochondria.

It is because the AMP-activated protein kinase phosphorylates the serine residues of acetyl-CoA carboxylase to inactivate it. If a mutation occurs in such residues, then the AMPL cannot phosphorylate acetyl-CoA carboxylase and this enzyme will get activated spontaneously.

In such a situation, there will be more than sufficient production of malonyl-CoA, which will inhibit the admittance of more fatty acid getting inside the mitochondria; this will indirectly prevent the oxidation of fatty acids.

Which statement distinguishes the light-dependent (L-D) reaction from the light-independent (L-IND) reaction?

Alja [10]

The correct answer is (a).

Both L-D and L-IND reactions take place in the chloroplast of the cell but in different parts or locations. L-D reactions take place in the chloroplast thylakoids while L-IND reactions take place in the chloroplast stroma.

Chloroplasts are chlorophyll- filled organelles mostly found in the leaves of green plants. Chloroplasts are surrounded by a double membrane called the thykaloid membrane that forms long folds within the organelle. In electron micrographs, the thykaloid membranes look like stacked coins. Chlorophyll is located within the thykaloid membranes.

Between the thykaloid membrane and the chloroplast membrane is a space. This space is what is called the stroma.

How would the introduction of a nonnative species most likely affect biodiversity in an ecosystem?

Bacterial species have evolved over millions of years to fill almost every available environmental niche on this planet. Despite

AVprozaik [17]

Answer:

1. Glucose breaks down into two pyruvates. CATABOLIC

2. Ammonia is added to glutamate to form glutamine. Anabolic

3. Four amino acids join to form tetrapeptides. Anabolic

4. A uracil base is added to an mRNA strand by RNA polymerase. Anabolic

5. Starches are digested into individual glucose molecules. CATABOLIC

6. Ribose and inorganic phosphate join together to form a nucleotide base. Anabolic

Explanation:

Chemical reactions are classified as anabolic and catabolic depending on whether they form or disintegrate structures, yielding energy to the medium or taking energy from the medium.

Anabolic reactions are those that take energy from the environment and therefore synthesize very complex molecules, of various bonds such as glycogen, starch, among other polysaccharides.

On the other hand, catabolism leads to the destruction of the unions of a chemical product, that is why they have greater entropy and is thus the greatest disorder.

Catabolism releases energy to the environment, it releases it.

For an anabolic reaction to happen, there must be a catabolic one, since it takes the energy released by catabolism, and for a catabolism to happen, an anabolism must first have arisen, that is, the formation of a molecule or particle that is dissociates.
