VERIFIED ANSWERS |GRADE A+|

1. In the process of glycolysis, what is the net yield of ATP per molecule of glucose
metabolized under anaerobic conditions?
A. 4 ATP
B. 36 ATP
C. 32 ATP
D. 2 ATP
Answer: D
Conceptual Explanation: Glycolysis produces 4 ATP but consumes 2 ATP in the initial
investment phase, resulting in a net yield of 2 ATP per glucose molecule.
2. Which metabolic pathway is responsible for the synthesis of glucose from non-
carbohydrate precursors such as glycerol and amino acids?
A. Glycogenolysis
B. Gluconeogenesis
C. Glycogenesis
,D. Glycolysis
Answer: B
Conceptual Explanation: Gluconeogenesis is the metabolic process by which organisms
produce sugars for catabolic reactions from non-carbohydrate precursors.
3. During the electron transport chain, what is the final electron acceptor at the end of the
aerobic respiration process?
A. Water
B. Oxygen
C. Carbon dioxide
D. NAD+
Answer: B
Conceptual Explanation: Oxygen acts as the final electron acceptor at the end of the
electron transport chain, where it combines with hydrogen ions to form water.
4. Which hormone is primarily responsible for shifting the body into the post-absorptive state
by stimulating glycogenolysis and lipolysis?
A. Insulin
B. Aldosterone
C. Thyroxine
D. Glucagon
, Answer: D
Conceptual Explanation: Glucagon is secreted by alpha cells of the pancreas when blood
glucose levels are low, promoting the breakdown of glycogen and fats for energy.
5. Deficiency in which fat-soluble vitamin is most closely associated with impaired blood
clotting and prolonged prothrombin time?
A. Vitamin A
B. Vitamin E
C. Vitamin K
D. Vitamin D
Answer: C
Conceptual Explanation: Vitamin K is a vital cofactor for the synthesis of several clotting
factors in the liver, including factors II, VII, IX, and X.
6. What is the primary hormonal driver of the absorptive state, facilitating the movement of
glucose into skeletal muscle and adipose tissue?
A. Insulin
B. Epinephrine
C. Cortisol
D. Growth Hormone
Answer: A
