Firstly, amylose and glycogen are converted to glucose. Deamination of ketogenic amino acids occur and these enter respiratory catabolism as intermediates.

1. Firstly, amylose and glycogen are converted to glucose. Deamination of ketogenic amino acids occur and these enter respiratory catabolism as intermediates.
2. Firstly, amylose and glycogen are converted to glucose. Deamination of ketogenic amino acids does not occur and these do not enter respiratory catabolism as intermediates.
3. Firstly, amylose and glycogen are converted to glucose. Deamination of ketogenic amino acids occur and these do not enter respiratory catabolism as intermediates.
4. Firstly, amylose and glycogen are not converted to glucose. Deamination of ketogenic amino acids occur and these enter respiratory catabolism as intermediates.

Correct answer: Firstly, amylose and glycogen are converted to glucose. Deamination of ketogenic amino acids occur and these enter respiratory catabolism as intermediates.

Solution

Amylose and glycogen are polysaccharides that are first hydrolyzed to glucose. Ketogenic amino acids are deaminated, and their carbon skeletons enter respiration as intermediates rather than being excluded from it.
