Detailed explanation-1: -Cellular respiration uses glucose and oxygen to make carbon dioxide, water, and ATP. The molecule ATP is used for energy to run cellular processes.
Detailed explanation-2: -Answer and Explanation: Cellular respiration is best described as E) changing of stored chemical energy in food molecules to a form usable by organisms.
Detailed explanation-3: -Glucose represents a monosaccharide, or simple sugar, with the chemical formula C6H12O6. Glucose is essential in living organisms because it serves as the primary reactant used in cellular respiration, in which a series of pathways produces ATP, the main energy source for cells.
Detailed explanation-4: -Which of the following statements best describes cellular respiration? Carbon-based molecules from food and oxygen are used to make ATP.
Detailed explanation-5: -Figure: Cellular Respiration: Glycolysis is the first pathway of cellular respiration that oxidizes glucose molecules. It is followed by the Krebs cycle and oxidative phosphorylation to produce ATP. Glycolysis is the first of the main metabolic pathways of cellular respiration to produce energy in the form of ATP.
