Question

Digestion is
A. Conversion of large food particles into small food particles
B. Conversion of small food particles into large food particles
C. Conversion of food into protoplasm
D. Conversion of non-diffusible food particles into diffusible food

Answer 1

The digestive enzymes and efficacy of an animal's digestive tract determine how much of a food is digested. cellulose, the basic chemical polymer in plant cell walls, is the most well-known of these indigestible substances. Cellulase, the enzyme required to breakdown cellulose, is not produced by most mammals. However, several animals and species have formed symbiotic interactions with bacteria that produce cellulase.

Complete answer:
Non-diffusible food particles are converted into diffusible food during digestion.
Large insoluble food molecules are broken down into little water-soluble food molecules during digestion, allowing them to be absorbed into the watery blood plasma. These tiny molecules are taken into the bloodstream by certain organisms through the small intestine. Digestion is a type of catabolism that is frequently separated into two processes: mechanical and chemical digestion.

As a result, option D is the correct answer.

The process of absorbing vitamins, minerals, and other compounds from food within the gastrointestinal tract as part of an organism's nutrition is known as assimilation. This is usually done in people with a chemical (enzymes and acids) and physical disintegration (oral mastication and stomach churning).

The chemical change of chemicals in the bloodstream by the liver or cellular secretions is the second process of bio absorption. Although a few comparable molecules can be absorbed through digestion bio absorption, many compounds' bioavailability is determined by this second phase, as both the liver and cellular secretions can have extremely distinct metabolic actions. This second process is where the absorbed food reaches the cells via the liver

Note:-
Mechanical and chemical procedures are used to complete the digestion process. Mastication of food and swallowing facilitation are two primary functions of the buccal cavity. The teeth and tongue masticate and fully combine the meal with the help of saliva. The mouth is where digestion begins. To make it easier to swallow, the food is crushed up by the teeth and moistened with saliva. Saliva also contains an enzyme, which begins the process of breaking down carbs into sugars.
