Which of the following terms describes glycogen catabolism?
Glycoproteins
Glycosaminoglycan
Glycogenolysis
Gluconeogenesis
The Correct Answer is C
a. Glycoproteins: Glycoproteins are proteins that have carbohydrate groups attached to them and are not related to glycogen breakdown.
b. Glycosaminoglycan: Glycosaminoglycans are long polysaccharide molecules involved in building connective tissues, not in glycogen catabolism.
c. Glycogenolysis: Correct. Glycogenolysis is the process of breaking down glycogen into glucose to be used for energy.
d. Gluconeogenesis: Gluconeogenesis is the process of producing glucose from non-carbohydrate sources, not the breakdown of glycogen.

Correct Answer is D
Explanation
a. Carrying oxygenated blood from the heart to the peripheral tissue: This describes the function of systemic arteries, not the pulmonary artery.
b. Carrying deoxygenated blood from the lungs to the heart: This describes the pulmonary veins, not the pulmonary artery.
c. Carrying oxygenated blood from the lungs to the left side of the heart: This describes the function of the pulmonary veins, not the pulmonary artery.
d. Carrying deoxygenated blood from the right side of the heart to the lungs: Correct. The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.
Correct Answer is A
Explanation
A. Loop of Henle:After the glomerular filtrate passes through the proximal convoluted tubule, it enters the Loop of Henle. This component of the nephron is responsible for further concentrating the filtrate and plays a critical role in urine concentration.
B. Bowman's capsule:Bowman's capsule is where glomerular filtration begins. It collects the filtrate from the glomerulus, but it is not where filtrate goes after the proximal convoluted tubule.
C. Collecting duct:The collecting duct is the final segment of the nephron where urine is collected after it has passed through the Loop of Henle and distal convoluted tubule. It does not receive the filtrate directly from the proximal convoluted tubule.
D. Glomerulus:The glomerulus is a network of capillaries where filtration of blood occurs, producing glomerular filtrate. It is not a component that the filtrate enters after the proximal convoluted tubule.
