Cellular Energy
Cellular Energy Chapter 9
| Question | Answer |
|---|---|
| ATP is the molecule that stores ___ for easy use within the cell. | energy |
| ATP is formed when a _____ group is added to ADP. | phosphate |
| When ___ is broken down, ADP and phosphate are formed and energy is released. | ATP |
| Green organisms trap the energy in sunlight and store it in the ___ of certain molecules for later use. | bonds |
| Organisms that cannot use sunlight directly obtain energy by consuming ____ or other organisms that have consumed plants. | plants |
| Photosynthesis is the process by which cells use light energy to make simple _____. | sugars |
| The light reactions of photosynthesis produce ____ and result in the splitting of water molecules. | ATP |
| The reactions of the ____ ____ make carbohydrates using CO2 along with ATP and NADPH from light reactions. | Calvin cycle |
| In cellular respiration, cells break down _____ to release energy. | carbohydrates |
| The first stage of cellular respiration is ____. | glycolysis |
| Glycolysis takes place in the cytoplasm and does not require _____. | oxygen |
| The citric acid cycle takes place in ____ and requires oxygen. | mitochondria |
| adenosine diphosphate | ADP |
| adenosine triphosphate | ATP |
| molecule formed from the breaking off of a phosphate group for ATP | ADP |
| When the phosphate group breaks off from ATP, what is released? | energy |
| the energy storing molecule in cells | ATP |
| What is ATP composed of? | an adenosine molecule, a ribose sugar, and 3 phosphate groups |
| What is the 2nd phase of photosynthesis? | the Calvin cycle |
| A series of reactions that use carbon dioxide to form sugars is called ______. | the Calvin cycle |
| Where does the Calvin cycle take place? | stroma of the chloroplast |
| Does the Calvin cycle require light? | no |
| What makes the Calvin cycle a cycle? | one of the last molecules formed in the series of chemical reactions is also one of the molcules needed for the first reaction of the cycle. Therefore, one of the products can be used again to continue the cycle. |
| What are the molecules that absorb specific wavelengths of sunlight? | pigments |
| Which pigment is most common in photosynthesis? | chlorophyll |
| Does chlorophyll absorb green? What gives chlorophyll a green appearance? | no; it reflects the green wavelengths since it doesn't absorb them |
| What is the process that uses the sun's energy to make simple sugars called? | photosynthesis |
| What are the 2 phases of photosynthesis? | light-dependent reactions and light independent reactions |
| Is the Calvin cycle light dependent or light independent? | light independent |
| What is the electron transport chain? | a series of proteins embedded in the thylakoid membrane that passes energized electrons along to the next protein |
| What is the reaction that takes place in the thylakoid membrane of a chloroplast during light-dependent reactions where 2 molecules of water are split to form oxygen, hydrogen ions, and electrons? | photolysis |
| What is the electron carrier molecule? | NADP+ |
| What type of chemical reaction requires the presence of oxygen? | aerobic |
| What type of chemical reaction does not require the presence of oxygen? | anaerobic |
| What is the chemical process where mitochondria break down food molecules to produce ATP? | cellular respiration |
| What is the series of anaerobic chemical reactions in the cytoplasm that breaks down glucose into pyruvic acid? | glycolysis |
| What are the 3 stages of cellular respiration? | glycolysis, the citric acid cycle, and the electron transport chain |
| What's another name for the citric acid cycle? | Kreb's cycle |
| Name one of the processes that supplies energy when oxygen is scarce. | lactic acid fermentation |
| Which type of fermentation is used by yeast cells and some bacterial to produce CO2 and ethyl alcohol? | alcoholic fermentation |
| Where is lactic acid produced? | muscle cells during strenuous exercise |
| What causes the feeling of muscle fatigue after strenuous exercise? | the build up of lactic acid in the muscle cells |
