| Question | Answer |
|---|---|
| Most of the energy used by life on Earth comes from the | Sun |
| Organisms that are not producers | must consume other organisms to get energy |
| Light energy is converted to chemical energy through the process of | photosynthesis |
| What organism does not carry out photosynthesis | animals |
| ATP is composed of a nitrogenous base, a sugar, and | three phosphate groups. |
| ATP is called a cell's energy "currency" because | ATP can be "made" in one place and "spent" in another. |
| When a phosphate group is removed from an ATP molecule | a substantial amount of energy is released |
| The space inside the inner membrane of a chloroplast is called the | stroma |
| Chlorophyll is green because | it reflects green wavelengths of light |
| The major atmospheric by-product of photosynthesis is | oxygen |
| Because of photosynthesis | the atmosphere is rich in oxygen gas |
| The source of oxygen produced during photosynthesis is | water |
| Products of the light reactions of photosynthesis that are required by the dark reactions are | ATP and NADPH |
| What is not true about dark reactions of photosynthesis | use water as an electron source |
| The energy used in the Calvin cycle for production of sugar molecules come from | ATP and NADPH |
| Carbon dioxide is converted into organic compounds in the | Calvin cycle |
| During the final stage of photosynthesis, sugars are produced from | carbon dioxide |
| When glycolysis occurs | a molecule of glucose is split |
| The process of cellular respiration | breaks down food molecules to release stored energy |
| What is the net gain of ATP molecules in glycolysis | 2 |
| Cellular respiration takes place in two stages; | glycolysis, then photosynthesis |
| What is not part of cellular respiration | the Calvin cycle |
| The name of the process that takes place when organic compounds are broken down in the absence of oxygen | fermentation |
| Fermentation enables glycolysis to continue under | anaerobic conditions |
| If oxygen is absent during the second stage of cellular respiration, | fermentation will occur |
| Cells produce ATP most efficiently in the presence of | oxygen |
| What process produces the most ATP | aerobic respiration |
| Which pigment reflects purple, pink, or red light waves | Anthocyanin |
| Which pigment reflects brown and yellow light waves | Tannins |
| Which pigment reflects orange yellow light waves | Chlorophyll |
| which pigment reflects green light waves | chlorophyll |
| The Krebs cycle happens in what part of the mitochondria | Matrix |
| Which phrase best describes the function of the ATP molecule? | carries energy |
| Where does the chemical energy to produce ATP come from? | the breakdown of food into smaller molecules |
| Energy is released from an ATP molecule for cellular processes when it | has a phosphate group removed |
| Which of the following statements best describes the process of photosynthesis | Chloroplasts absorb sunlight and store chemical energy |
| What is the term for an organism that makes its own source of chemical energy | A producer |
| The main light absorbing molecules found in plant leaves are called | Chlorophyll |
| The light independent reactions of photosynthesis nee | carbon dioxide |
| Which of the following takes place in the light dependent reactions of photosynthesis | Energy is captured |
| Where so the hydrogen ions for the photosystems of the light dependent reactions come from | water |
| Which phrase best describes the electron transport chain in photosynthesis | a series of proteins located in the thylakoid membrane |
| What is the relationship between the photosystems and the Calvin cycle | The photosystems transfer energy to the Calvin cycle through ATP and NADPH |
| Which of the following types of organisms uses cellular respiration for their cellular energy needs | Eukaryotes |
| Which process breaks down sugars to make ATP when oxygen is present | cellular respiration |
| The part of cellular respiration in which glucose is broken down is called | glycolysis |
| Two products of the Krebs cycle are | ATP and CO-2 |
| What provides the electron transport chain in cellular respiration with the energy it needs to function | Krebs cycle |
| Which of the following statements best describes cellular respiration | Carbon based molecules from food and oxygen are used to make ATP |
| Which of the following are end products of glycolysis? | pyruvate, NADH and ATP |
| What is the main function of the Krebs cycle? | producing molecules that carry high energy electrons to the electron transport chain |
| Which phrase about fermentation is correct | takes place without oxygen |
| Which end product of fermentation causes the burning feeling in muscles that are working hard? | lactic acid |
