NEET BIOLOGY

Detailed explanation-1: -Humans and animals get their glucose from plants. They consume food in the form of complex carbohydrates or starch. The enzymes produced in the body such as salivary amylase, maltase, and sucrase convert carbohydrates into absorbable glucose molecules.

Detailed explanation-2: -Plants form glucose by photosynthesis and animals get glucose by breaking down the food they eat. During cellular respiration, glucose combines with oxygen to release energy and to form carbon dioxide and water. Most of the carbon dioxide in animals is released into the air when the animal breathes.

Detailed explanation-3: -Animals that eat meat (carnivores) must get their glucose from the food they eat, which are animals that eat plants (herbivores). The glucose from the plant is transferred to their body tissues. When herbivores are then eaten by carnivores, their body tissues are broken down to provide a source of glucose. 30.

Detailed explanation-4: -The primary source of energy for animals is carbohydrates, primarily glucose: the body’s fuel. The digestible carbohydrates in an animal’s diet are converted to glucose molecules and into energy through a series of catabolic chemical reactions.

Detailed explanation-5: -Most animal’s only source of energy is through the breakdown of glucose. This glucose is produced by plants through photosynthesis.
