AP BIOLOGY

Detailed explanation-1: -Glucose is converted into ATP by cellular respiration. One molecule of glucose produces 38 ATP molecules by aerobic respiration in the cytoplasm and mitochondria. The steps involved in cellular respiration are glycolysis, Krebs cycle, and oxidative phosphorylation .

Detailed explanation-2: -Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.

Detailed explanation-3: -ATP. Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.

Detailed explanation-4: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Detailed explanation-5: -The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity.
