Pancreatic lipase:
Is called trypsin
Digests lipids to fatty acids and glycogen
Digests fats to fatty acids
Is inactivated by bile
The Correct Answer is C
A. Is called trypsin: Trypsin is a pancreatic enzyme, but it digests proteins, not fats.
B. Digests lipids to fatty acids and glycogen: Glycogen is related to carbohydrate storage, not a product of fat digestion.
C. Digests fats to fatty acids: Pancreatic lipase breaks down triglycerides into fatty acids and monoglycerides for absorption.
D. Is inactivated by bile: Bile actually emulsifies fats, making them more accessible to pancreatic lipase, not inactivating it.

Correct Answer is B
Explanation
A. Aldosterone: Aldosterone is secreted by the adrenal glands, and it regulates sodium and water balance, not in response to low oxygen.
B. Erythropoietin: The kidneys secrete erythropoietin in response to hypoxia to stimulate the production of red blood cells in the bone marrow.
C. Converting enzyme: Refers to angiotensin-converting enzyme (ACE), which is found in the lungs and converts angiotensin I to II—not secreted by kidneys in response to hypoxia.
D. Renin: Renin is secreted by the kidneys in response to low blood pressure or sodium, not oxygen deficiency.
Correct Answer is D
Explanation
A. Glucose is used up by the metabolizing nephron units: Nephrons do not metabolize all glucose; their role is to filter and reabsorb.
B. Glucose cannot be filtered: Glucose is a small molecule and is easily filtered by the glomerulus.
C. Glucose is converted to ammonia and excreted as urea: This describes protein metabolism, not glucose.
D. All filtered glucose is reabsorbed: In healthy kidneys, 100% of filtered glucose is reabsorbed in the proximal tubule, so none appears in urine unless blood levels are too high (e.g., diabetes).
