| Question | Answer |
|---|---|
| autotroph | an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. |
| cellular respiration | the process by which cells derive energy from glucose. |
| consumer | a person who consumes a product or service. |
| energy | the force that causes things to move. |
| food | any substance consumed by an organism for nutritional support. |
| glucose | A type of sugar; the chief source of energy for living organisms. |
| heterotroph | an organism that eats other plants or animals for energy and nutrients. |
| photosynthesis | A chemical process that occurs in plants, algae, and some types of bacteria, when they are exposed to sunlight. |
| producer | an organism that makes its own food |
| Calvin cycle | a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. |
| chemosynthesis | the process by which food is made by bacteria or other living things using chemicals as the energy source, typically in the absence of sunlight. |
| chlorophyll | the green pigment in plants, algae, and cyanobacteria that is essential for photosynthesis. |
| electron transport chain | a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy. |
| grana | the components found inside chloroplasts of the plant cells. |
| light reactions | the first stage of photosynthesis. |
| photosynthesis | A chemical process that occurs in plants, algae, and some types of bacteria, when they are exposed to sunlight. |
| stroma | The cells and tissues that support and give structure to organs, glands, or other tissues in the body. |
| thylakoid membrane | an internal system of interconnected membranes, that carry out the light reactions of photosynthesis. |
| aerobic respiration | the process by which cells convert glucose and oxygen into ATP (energy), carbon dioxide, and water. |
| anaerobic respiration | a process that produces ATP in the absence of oxygen . |
| glycolysis | A process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen. |
| Krebs cycle | is a series of biochemical reactions that help in breaking down and releasing energy stored in food through the oxidation of acetyl-CoA which is derived from carbohydrates, proteins, lipids, and alcohol.Jan |
| alcoholic fermentation | a biochemical process that converts sugars and other carbohydrates into alcohol and carbon dioxide through the action of microorganisms, primarily yeast or bacteria. |
| fermentation | the process in which a substance breaks down into a simpler substance. |
| lactic acid fermentation | a type of anaerobic respiration (or fermentation) that breaks down sugars to produce energy in the form of ATP. |
