The synthesis of an amino acid follows this pathway: precursor A → intermediate B → amino acid C. Each reaction is catalyzed by a different enzyme. This metabolic pathway is controlled by feedback inhibition with amino acid C inhibiting the conversion of precursor A to intermediate B. Amino acid C acts as a _____ of the first enzyme in the pathway.

Answer 1
Answer:

Answer:

The synthesis of an amino acid follows this pathway: precursor A → intermediate B → amino acid C. Each reaction is catalyzed by a different enzyme. This metabolic pathway is controlled by feedback inhibition with amino acid C inhibiting the conversion of precursor A to intermediate B. Amino acid C acts as a noncompetitive inhibitor of the first enzyme in the pathway.

Explanation:

A no-competitive inhibitor reduces the activity of an enzyme by binding at its active site although it has already bound to the corresponding substrate
Answer 2
Answer:

Final answer:

Amino acid C acts as a noncompetitive inhibitor, regulating its own production via feedback inhibition. This is a common mechanism used in metabolic pathways to maintain balance.

Explanation:

In the described pathway, amino acid C regulates its own production by inhibiting the first step of the pathway. This is an example of a regulatory mechanism called feedback inhibition. Essentially, when there's plenty of amino acid C present, it will bind to the first enzyme in the pathway, preventing its action and thus stopping more of amino acid C from being produced. So, in this scenario, amino acid C is acting as a noncompetitive inhibitor of the first enzyme in the pathway.

The process of heat transfer thought to be responsible for the movement of the lithospheric plates on the surface of the earth is

Answers

Answer:

Convection

Explanation:

Difference in temperature induces convection currents. The mantle material close to Earth's core is quite hot in comparison to the one close to the lithosphere, which is cooler. Earth's convection currents are very slow in movement. They flow at rates of a few centimeters per year. It is believed by scientists that the movement of mantle material carries the plates of the lithosphere with it which causes the plates to move.

Answer:

The answer is Convection

Explanation:

Plate movement happens because of a process of heat transfer called convection. Convection is the movement produced when a gas, liquid, or plastic is unevenly heated.

Mendel crossed two plants that were heterozygous for purple flower color. Which genotypes could he have used to represent the cross?

Answers

The answer is two Pp genotypes.

If we imagine that plant has two alleles for the trait and if P represents dominant allele, and p represents recessive allele, then genotypes are:
PP - dominant homozygous, which contains both dominant alleles
pp - recessive homozygous, which contains both recessive alleles
Pp - heterozygous, which contains both dominant and recessive alleles

Place the components in order, from smallest to largest.
A) A0B0D0C
B) B0C0D0A
C) C0D0B0A
D) D0C0B0A

Answers

since gene has multiple codons 
and codon has 3 sequence of nucleotides, 

The smallest would be a DNA nucleotide , then a codon, then a gene and finally a chromosome!

so the answer is B
