1). A process by which food is broken down with oxygen is called ______.

2). ______This cell organelle has a double membrane and stores energy in the form of nutrients that the cell can use for energy.

3).______stands for adenosine triphosphate. It is the energy-storage compound in cells. Energy is released when the bonds are broken.

4). In ______, cells release energy from food molecules. The cells takes in oxygen and release carbon dioxide as a waste product.

5). ______is the principal pigment of green plants.

6). ______is a colored chemical compound that absorbs light from the sun.

7). ______is a type of fermentation in which food is broken down without the oxygen. In this process, less energy is required.

8). ______is the process in which cells capture energy from the sun and use that energy to make food molecules.

9). In the ______, green plant pigment harvests energy from sunlight. This cell organelle if only found in plant cells.

10). ______is the process by which pyruvic acid is converted to alcohol and carbon dioxide.

11.______is the conversion of pyruvic acid to lactic acid.
