1. Unit 3 Photosynthesis & Cellular Respiration
11 Words

2. ATP
Compound used by cells to store and release convenient energy needed to conduct all of life’s processes.

3. ADP
Compound that results after energy is released when a high-energy phosphate-bond is broken.

4. Photosynthesis
Two-Phase anabolic pathway in which the sun’s light energy is converted to chemical energy for use by the cell.

5. light-dependent reactions occur.
Thylakoid
In chloroplasts, one of the stacked, flattened, pigment containing membranes in which
light-dependent reactions occur.

6. Chlorophyll
The pigment that absorbs red, orange, yellow, blue, indigo & violet light for photosynthesis but that reflects green light.

7. Stroma Fluid-filled space outside the grana in which
light-independent reaction takes place.

8. Cellular Respiration
Catabolic pathway in which organic molecules (food) are broken down to release energy (ATP) for use by the cell.

9. Metabolism
The combined chemical reactions occurring in a living thing in which molecules are being built up and broken down.

10. Aerobic
A process that
requires oxygen.

11. A process that does not require oxygen.
Anaerobic
A process that does not require oxygen.

12. Fermentation
The process by which cells obtain energy (for small amounts of ATP) from food molecules in the absence of oxygen.
