Question

1. the two forms of energy are _ and _. 2. the sum of all chemical reactions in a cell is called _. 3. a reaction that absorbs energy is called an _ reaction. 4. a reaction that releases energy is called an _ reaction. 5. the passive movement of molecules is called _. 6. _ is the process where the end product inhibits an earlier step in a p 7. passive transport moves substances from _ to _ concentration. 8. active transport moves substances from _ to _ concentration. 9. the molecule that stores energy in cells is _. 10. the three subatomic particles are protons, neutrons, and _.

Explanation:

1. Energy exists in potential and kinetic forms.
2. Metabolism encompasses all cell - chemical reactions.
3. Endothermic reactions absorb energy.
4. Exothermic reactions release energy.
5. Diffusion is passive molecular movement.
6. Feedback inhibition is when end - product inhibits an earlier step.
7. Passive transport is from high to low concentration.
8. Active transport is from low to high concentration.
