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 B
Explanation
A. Hypernatremia: Hypernatremia refers to high sodium levels, which are not directly related to impaired glucose metabolism.
B. Hyperglycemia: Aging reduces insulin sensitivity and pancreatic function, leading to higher blood glucose levels, or hyperglycemia, which is a risk factor for diabetes mellitus.
C. Hypoglycemia: Aging-related insulin resistance typically results in elevated glucose levels (hyperglycemia), not low blood sugar (hypoglycemia).
D. Hyperkalemia: Hyperkalemia is an excess of potassium in the blood, which is not directly linked to impaired glucose metabolism.
Correct Answer is D
Explanation
A. Regeneration: Regeneration refers to the complete replacement of damaged tissue with the same type of cells, which is different from scar formation.
B. Sarcoma: Sarcoma is a type of malignant tumor originating in connective tissue, not a process of scar formation.
C. Meninges: The meninges are protective membranes surrounding the brain and spinal cord; they are unrelated to scar tissue formation.
D. Fibrosis: Fibrosis is the process of scar tissue formation when normal tissue is replaced by fibrous connective tissue after an injury.
