EVERYDAY SCIENCE

Detailed explanation-1: -Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body’s cells. Initially, the sugars in the food you eat are digested into the simple sugar glucose, a monosaccharide. Recall that glucose is the sugar produced by the plant during photosynthesis.

Detailed explanation-2: -It comes from the glucose in foods that you eat! Energy is stored in the chemical bonds of the glucose molecules. Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use.

Detailed explanation-3: -When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.

Detailed explanation-4: -Aerobic respiration Glucose is the molecule normally used for respiration-it is the main respiratory substrate .

Detailed explanation-5: -Amino acids, lipids, and other carbohydrates can be converted to various intermediates of glycolysis and the citric acid cycle, allowing them to slip into the cellular respiration pathway through a multitude of side doors.
