Natural selection increases the frequency of beneficial alleles in

Biology

uysha [10]3 years ago

Natural selection leads to increases in the mean fitness of populations and so will reduce the frequency of disease-associated alleles, but other evolutionary processes, such as mutation and gene flow, may introduce or increase the frequency of these deleterious alleles.

Which enzyme(s) involved in fatty acid synthesis utilize ATP? Select all that apply.
GREYUIT [131]

Answer:

a. Acetyl CoA carboxylase  

Explanation:

Much of the fatty acids used by the body is supplied by the diet, excessive amounts of carbohydrates and protein obtained from the diet can be converted to fatty acids and stored as triglycerides. Fatty acid synthesis occurs mainly in the liver and mammary glands, and to a lesser extent in adipose tissue and kidney, the process incorporates acetyl CoA carbons into the forming fatty acid chain using ATP and NADPH.

The acetyl portion of acetyl CoA is transported to cytosol as citrate, produced by condensation of oxaloacetate and acetyl CoA, the first reaction of the citric acid cycle, this occurs when the concentration of mitochondrial citrate is high, observed when there is a high concentration of ATP and isocitrate dehydrogenase is inhibited.  The increase of citrate and ATP favors the synthesis of fatty acids, since this pathway needs both. Acetyl CoA should be converted to malonyl CoA. Carboxylation is catalyzed by acetyl CoA carboxylase and requires ATP, this reaction is the regulated step in fatty acid synthesis: it is inactivated by products, malonyl CoA and palmitoyl CoA, and activated by citrate, another regulatory mechanism is reversible phosphorylation of enzyme, which makes it inactive due to the presence of adrenaline / glucagon

Put the following events in the correct order:
Wewaii [24]

Answer:

Explanation:

c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.

b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.

The process of deoxyribonucleic acod starts with replication to transcription and translation.

Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.

transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.

Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

Hence the arrangement is from C ---- A-----B.
