Most of the energy used by life on Earth comes from the | sun |
Organisms that are not autotrophs | must consume other organisms to get energy |
Light energy is converted to chemical energy through the process of | photosynthesis |
Which of the following organisms do not carry out photosynthesis | animals |
ATP is composed of a nitrogenous base, a sugar, and | 3 phosphate groups |
chloroplasts : photosynthesis :: | mitochondria : cellular respiration |
photosynthesis : oxygen :: | cellular respiration : carbon dioxide |
When cells break down food molecules, energy is | stored temporarily in ATP molecules |
ATP is called a cell's energy "currency" because | ATP can be "made" in one place and "spent" or used in another |
When a phosphate group is removed from an ATP molecule, | a substantial amount of energy is released |
Low temperature may cause photosynthesis to occur | more slowly |
When glycolysis occurs, | a molecule of glucose is split |
What is the net gain of ATP molecules in glycolysis | 2 |
The name of the process that takes place when organic compounds are broken down in the absence of oxygen is | fermentation |
Fermentation enables glycolysis to continue under | anaerobic conditions |
Cells produce ATP most efficiently in the presence of | oxygen |
Which of the following processes produces the most ATP | aerobic respiration |
The ultimate source of energy for all life on Earth is the | sun |
Energy from the sun enters living systems through ______ such as plants and certain prokaryotes | autotrophs |
Animals get energy from food through the process of | cellular respiration |
Of the different inputs and products of photosynthesis, the most stable form of _____ is carbon dioxide | carbon |
Of the inputs and outputs of cellular respiration, the less stable carbon compound is | glucose |
Organisms extract energy stored in glucose through the process of cellular | respiration |
______ is the organic molecule that is the main energy source for cell processes and is made with the energy released from the breakdown of glucose | ATP |
______ is the energy "currency" of a cell | ATP |
During the first stage of photosynthesis, ______ is absorbed by chlorophyll | light energy |

Products of dark reactions during photosynthesis | ATP AND NADPH |
During the final stage of photosynthesis, sugars are made from | carbon dioxide |
Fermentation enables glycolysis to occur under | aerobic |
The total amount of ATP depends on | oxygen |
Energy lost in the electron transport chain is used to pump | hydrogen |
During fermentation, alcoholic and carbon dioxide; other produces | lactic acid |
Glucose is split during what | glycolysis |
