Detailed explanation-1: -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-2: -Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy.

Detailed explanation-3: -3: Cellular respiration takes place in the stages shown here. The process begins with Glycolysis. In this first step, a molecule of glucose, which has six carbon atoms, is split into two three-carbon molecules. The three-carbon molecule is called pyruvate.

Detailed explanation-4: -In eukaryotes, most energy derives from aerobic (oxygen-requiring) processes, which start with a molecule of glucose. The glucose is broken down first through the anaerobic process of glycolysis, leading to the production of some ATP and pyruvate end-product.

Detailed explanation-5: -Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP . Generally speaking, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
