1. Answer: Option B
and D are correct
Explanation:
Amino acids are deaminated to produce keto acids that can enter
glycolysis or the TCA cycle.
Examples:
Alanine -----> Pyruvate ------> Glycolysis
Glutamine -----> Oxaloacetate ------> TCA cycle
2. Answer: Option A
is correct
Explanation:
Endocrine signaling: The signal is transported by the blood to
distantly located regions of the body from the secreting organ.
