If a tRNA had an AGC, it could base-pair to a(n).

A. glycogenesis:Glycogenesis is the process of converting glucose into glycogen for storage in the liver and muscles. When an endurance runner “carbo-loads,” she increases glycogen stores to provide a readily available energy source during prolonged exercise.

B. glycolysis:Glycolysis is the breakdown of glucose into pyruvate to produce ATP for immediate energy needs. It does not refer to storing glucose for future use, as occurs during carbo-loading.

C. gluconeogenesis:Gluconeogenesis is the formation of glucose from noncarbohydrate sources such as amino acids and glycerol, typically occurring during fasting or low-carbohydrate intake, not during carbohydrate loading.

D. glycogenolysis:Glycogenolysis is the breakdown of glycogen into glucose to supply energy during fasting or exercise, which is the opposite of the storage process during carbo-loading.

A. chondrocyte:Chondrocytes are specialized cells found in cartilage tissue. They produce and maintain the cartilaginous extracellular matrix and are not present in areolar connective tissue.

B. mast cell:Mast cells are abundant in areolar connective tissue and play a key role in inflammation by releasing histamine and other chemical mediators during immune responses.

C. macrophage:Macrophages are present in areolar connective tissue, where they function in phagocytosis to remove pathogens, debris, and damaged cells.

D. fibroblast:Fibroblasts are the most common cells in areolar connective tissue. They produce fibers such as collagen and elastin, as well as the extracellular matrix that provides structural support.
