Question

In cockroach which one is absorbed in hepatic caeca
A. Glucose and amino acids
B. Lipids
C. Glucose
D. Both B and C

Answer 1

Hint: Hepatic caeca produce digestive enzymes that take part in the digestion of food occurring in the mesenteron. The digestive enzymes include gastric amylase, maltase, invertase tryptase, and lipase. With the help of these, the digestion of carbohydrates, proteins, and fats is completed. In the cockroach, both Glucose and amino acids are absorbed in hepatic caeca.

Complete answer:
Option A- Glucose and amino acids
An amino acid that can be converted into glucose through gluconeogenesis is known as a glucogenic amino acid.

Option B- Lipids
Lipids are molecules containing hydrocarbons. They make up the building blocks of the structure and function of living cells. Examples of fats, oils, waxes, certain vitamins (such as A, D, E, and K), hormones, and most of the cell membrane that is not made up of protein.

Option C- Glucose
Glucose is a subcategory of carbohydrates and the most abundant monosaccharide. It is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight. It is used to make cellulose in cell walls, which is the most abundant carbohydrate.

Option D- Both B and C
These are lipids and glucose. Option D is incorrect as in cockroach Glucose and amino acids are absorbed in hepatic caeca.

Hence, the correct answer is option (A).

Note: Hepatic caecum is used in describing various physiological structures in some crustaceans, insects, and cephalochordates. "Hepatic" applies to the liver, and the hepatic caecum performs some functions that are analogous to the functions of the liver in vertebrates.
