Respiration

What is the combined net gain of ATP molecules at the completion of reactions A and B

36 ATP

Cellular respiration in humans occurs in

All cells of the body

What happens to certain nutrient molecules after they pass into muscle cells

They are acted on by enzymes and release the energy they contain

When organisms break the bonds of organic compounds, the organisms can

Use the energy obtained to digest molecules produced by respiration that uses oxygen

One type of anaerobic respiration results in the production of

alcohol and carbon dioxide

Bacteria that can survive without oxygen are described as

anaerobic

Which phrase best describes cellular respiration?

changing of stored chemical energy in food molecules to a form usable by organisms

Respiration is best described as a process by which

chemical energy is converted into a usable form

To remain healthy organisms must be able to obtain materials, change the materials, move the materials around, and get rid of waste. These activities directly require

energy from ATP

ATP is a compound that is synthesized when

energy stored in chemical bonds is released during cellular respiration

Which organic compound is found in most cells?

glucose

In heterotrophs, energy for the life processes comes from the chemical energy stored in the bonds of

organic compounds

The energy found in ATP molecules synthesized in animal cells comes directly from

organic compounds
