Answer 1

Answer:

Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. ... In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.

Explanation:

Answer 2

Answer:

A glucose molecule gradually decomposes into carbon dioxide and water during cellular respiration.

Explanation:

Through the process of cellular respiration, the energy of food is converted into energy that the body's cells can use. During cellular respiration, glucose and oxygen are converted to carbon dioxide and water, and energy is converted to $ATP$. Cellular respiration is an aerobic process by which living cells break down glucose molecules, releasing energy and forming $ATP$ molecules. ...in this step, the enzyme splits the glucose molecule into two he pyruvate molecules, releasing energy that is transferred.

As we have seen, cells require a constant supply of energy to create and maintain the biological order that sustains life. This energy is derived from the chemical bond energy of food molecules and serves as fuel for cells. Sugars are particularly important fuel molecules and are oxidized in small steps to form carbon dioxide $(CO)_{2}$ and water. In this section, we trace the main steps in the breakdown or catabolism of sugars and show how sugars generate $ATP$, $NADH$, and other activated carrier molecules in animal cells. In most animal cells, glucose dominates energy production, so the focus is on breaking down glucose. A very similar pathway operates in plants, fungi, and many bacteria. Other molecules such as fatty acids and proteins also serve as energy sources as they pass through the appropriate enzymatic pathways.

When $ATP$ is broken down by an enzyme ($ATPase$), energy is obtained from breaking the final phosphate bond. This energy can be used as the energy released in an exothermic reaction. It can be used for muscle contraction, or used internally, or absorbed endothermically within the cell to rebind phosphate to $ADP$ and regenerate $ATP$. This is because it stores only the $ATP$ needed for exercise.

This are some reasons why cells break down into glucose and uses the released energy to make the $ATP$
