Which of the following human digestive enzymes is secreted in an inactive form and is activated by the enzyme enterokinase? MCQ with Answer and Explanation

Explanation:
Histology is the microscopic study of tissues—groups of cells with similar structure and function. Cytology deals with cells, anatomy with gross body structures, morphology with form and external features. Histological techniques involve staining and microscopy to examine tissue architecture in health and disease.

Explanation:
Convergent evolution occurs when distantly related organisms independently evolve similar traits or structures to adapt to similar ecological niches or environmental pressures. The resulting structures are called analogous organs (e.g., wings of birds and insects, eyes of octopuses and mammals). Divergent evolution is when related species evolve different traits (homologous organs). Coevolution is when two species evolve in response to each other.

Explanation:
Lipase is the fat-digesting enzyme, produced mainly by the pancreas (pancreatic lipase) and also by lingual and gastric glands. It hydrolyzes triglycerides into monoglycerides and free fatty acids. Bile salts emulsify fats, increasing surface area for lipase action. Amylase digests starch, pepsin digests proteins, sucrase hydrolyzes sucrose. Lipase requires colipase for optimal activity.
