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
