Cellular Respiration and Energy Production Quiz

Cellular respiration is a process of energy conversion that releases energy from food in the presence of oxygen.

Cells break down food molecules gradually to capture a little bit of chemical energy every step along the way and to use the energy stored in foods like glucose to synthesize compounds such as ATP.

Cellular respiration requires oxygen and a food molecule such as glucose.

<p>If cellular respiration took place in just one step, all of the energy from glucose would be released at once, and most of it would be lost in the form of light and heat.</p> Signup and view all the answers

<p>A living cell controls the energy by releasing the explosive chemical energy in food molecules a little bit at a time, trapping the energy in the form of ATP.</p> Signup and view all the answers

<p>The purpose of breaking down food molecules gradually in cellular respiration is to capture a little bit of chemical energy every step along the way, enabling cells to use the energy stored in foods like glucose to synthesize compounds such as ATP that directly power the activities of the cell.</p> Signup and view all the answers
