Which of the following best describes what hormones and hemoglobin are made with?

Lipids

Glucose

Proteins

Carbohydrates

Answer and Explanation

The Correct Answer is C

A. Lipids: Some hormones (e.g., steroid hormones like estrogen and testosterone) are lipid-based, but not all. Hemoglobin is a protein, not a lipid.

B. Glucose: Glucose is a carbohydrate used for energy, not for building hormones or hemoglobin.

C. Proteins: Hormones (such as insulin and growth hormone) and hemoglobin (which carries oxygen in red blood cells) are protein-based molecules essential for bodily functions.

D. Carbohydrates: Carbohydrates provide energy but do not contribute to the structure of proteins like hormones and hemoglobin.

Correct Answer is C

Explanation

A. Serous: Serous membranes line closed body cavities (e.g., pericardium, pleura, peritoneum) and do not open to the exterior.

B. Cutaneous: The cutaneous membrane is the skin, which covers the body but does not line internal passages.

C. Mucous: Mucous membranes line body cavities and passages that are open to the external environment, such as the respiratory, digestive, and urogenital tracts.

D. Synovial: Synovial membranes line joint cavities and produce synovial fluid for lubrication, but they do not line external body passages.

A. Formation of large amounts of ATP B. Muscle soreness C. Formation of ketone bodies D. Anaerobic breakdown of glucose

Correct Answer is D

Explanation

A. Formation of large amounts of ATP: Large ATP production occurs in aerobic respiration, not anaerobic metabolism. Lactic acidosis happens when there is a lack of oxygen and insufficient ATP production.

B. Muscle soreness: While lactic acid buildup may contribute to temporary muscle discomfort, muscle soreness alone does not indicate lactic acidosis, which is a systemic condition.

C. Formation of ketone bodies: Ketone bodies are produced during fat metabolism (e.g., in diabetic ketoacidosis), not anaerobic glucose metabolism.

D. Anaerobic breakdown of glucose: When oxygen levels are low, cells undergo anaerobic respiration, converting glucose to lactic acid instead of completely breaking it down through aerobic respiration. This leads to lactic acidosis.
