EVERYDAY SCIENCE

Detailed explanation-1: -The first is glucose, which comes from the food you eat. Glucose is a form of sugar that initiates glycolysis, the first step in cellular respiration. Glucose is converted into the organic compound called pyruvic acid, or pyruvate, which is both the byproduct of glycolysis and the initiator of the Krebs cycle.

Detailed explanation-2: -Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy. One molecule of glucose can produce a net of 30-32 ATP.

Detailed explanation-3: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.

Detailed explanation-4: -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-5: -The calvin cycle uses six molecules of carbon dioxide, 18 molecules of ATP, and 12 molecules of NADPH to produce one molecule of glucose.
