Photosynthesis
ATP
Mitochondria
Anaerobic Respiration
Chloroplast
Chlorophyll
Pigment
Cellular Respiration
Aerobic Respiration
Alcoholic Fermentation
Lactic Acid Fermentation
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.
