Lactic acidosis develops in response to:
Formation of large amounts of ATP
Muscle soreness
Formation of ketone bodies
Anaerobic breakdown of glucose
The Correct Answer is D
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.

Correct Answer is C
Explanation
A. Connective: Connective tissue provides support and structure (e.g., tendons, cartilage) but is not muscle tissue.
B. Cardiac: Cardiac muscle, found in the heart, is involuntary and contracts rhythmically without conscious control.
C. Skeletal: Skeletal muscle is the only voluntary muscle tissue, meaning it is consciously controlled. It allows movement of the body by attaching to bones via tendons.
D. Smooth: Smooth muscle, found in internal organs (e.g., intestines, blood vessels), is involuntary and controlled by the autonomic nervous system.
Correct Answer is D
Explanation
A. Unsaturated fats (HDL): High-density lipoprotein (HDL) is considered "good cholesterol" because it helps remove LDL cholesterol from the blood, reducing the risk of heart disease.
B. Omega-3 fatty acids: Omega-3 fatty acids are healthy fats that reduce inflammation and lower the risk of heart disease by improving heart health.
C. Omega-6 fatty acids: While excessive omega-6 intake may contribute to inflammation, they are not the primary contributors to plaque buildup in blood vessels like saturated fats (LDL).
D. Saturated fats (LDL): Saturated fats increase low-density lipoprotein (LDL), also known as "bad cholesterol," which contributes to plaque buildup in arteries and increases the risk of heart disease.
