C. Epididymis
D. Prostate gland and seminal vesicles

Explanation:
Pancreatic amylase, secreted into the duodenum, continues starch digestion initiated by salivary amylase, producing maltose and dextrins. Maltase then breaks maltose to glucose. Sucrase acts on sucrose.
Explanation:
Approximately 70% of CO2 is transported in the blood as bicarbonate ions (HCO3-). CO2 diffuses into red blood cells, where it reacts with water to form carbonic acid, catalyzed by the enzyme carbonic anhydrase. Carbonic acid then dissociates into H+ and HCO3-, which moves into the plasma. About 20-25% is carried as carbaminohemoglobin.
