Sorry if it isn't right.
Answer:
The correct answer is b glucose is broken down into two pyruvate molecules.
Explanation:
Krebs cycle is one of the most important step of aerobic respiraion.Krebs cycle occur within mitochondrial matrix.During krebs cycle the acetyl CoA generated from pyruvate reacts with oxalo acetate in a cyclic manner to regenerate 4 carbon compound oxaloacetate.
During krebs cycle pyruvate is broken down or oxidized to form 2 carbon compound known as acetyl CoA and carbon dioxide as byproduct.
But the breakdown of glucose into two pyruvate molecules occur during glycolysis.
Amino group
The term "amino acid" refers to an amino acid with an amino group immediately linked to the -carbon. These contain the secondary amines proline and hydroxyproline. They were previously frequently referred to as amino acids, which is incorrect because they lack the imine grouping HN=C. The archaic phrase is still used often.
The building blocks of proteins are amino acids, which are the chemical compounds that come together to make proteins. These biomolecules are essential for human growth and development and are engaged in a number of biological and chemical processes in the body. In nature, there are around 300 amino acids.
