Cell energy
| Question | Answer |
|---|---|
| What is the source of energy for almost all ecosystems? | Sunlight |
| What is the connection between light energy and ATP? | occurs in the light dependent reactions of photosynthesis |
| What is the relationship between ADP and ATP? | a fundamental energy cycle in cells |
| explain the relationship of ADP and ATP using a battery analogy | ATP is the fully charged battery, containing 3 phosphate groups and storing high-energy bonds, ADP is the is the recharging battery, with only 2 phosphate groups and less available energy |
| What does photosynthesis achieve? | to capture light energy and convert it into chemical energy |
| How does photosynthesis achieve this goal? | by using light energy, water, and carbon dioxide to produce glucose and oxygen through light dependent reactions and the Calvin cycle. |
| What are the atoms doing in photosynthesis? | Atoms of carbon, hydrogen, and oxygen from carbon dioxide and water are rearranged to form glucose, a sugar that stores energy and oxygen |
| What is the energy doing in photosynthesis? | light energy is captured by pigments like chlorophyll and used to power chemical reactions that convert carbon dioxide and water into glucose and oxygen. |
| what is the photosynthesis equation? | 6water+6carbon dioxide-SUNLIGHT-6oxygen+glucose |
| Where does photosynthesis occur? | In the chloroplast, found in the cells of a plant, algae, and some bacteria |
| What is the function of chlorophyll and where is it found in cells? | Chlorophyll is a pigment found in the chloroplasts of cells. it absorbs light from the sun and turns it into chemical energy the plant can use as food. |
| What is the ulimate goal of cellular respiration? | To produce ATP |
| How does cellular respirtation achieve it's goal | by breaking down glucose into simpler molecules, such as carbon dioxide and water, in a multi-stage process that transfers the stored chemical energy in ATP |
| What are the atoms doing in cellular respiration? | atoms from glucose and oxygen rearrange to form new molecules |
| What is the energy doing in cellular respiration? | energy from broken down food molecules is captured to create ATP |
| what is the cellular respiration equation? | glucose+6oxygen---6carbon dioxide+6water+36ATP |
| Where does cellular respiration occur? | in the cytoplasm and mitochondria of a eukaryotic cell |
| identify the parts of a plant that undergo photosynthesis and those that do not and how this relates to organelle structure | parts that lack a chloroplast, such as the root, and older, non green parts do not perform photosynthesis. leaves, green stems, and other green tissues do. chloroplast contains chlorophyll which absorbs light energy which is essential for photosynthesis |
| explain the difference between the different type of animal cells function and the number of mitochondria present in those cells | cells with high energy needs such as a heart, liver or muscle contain many mitochondria to make ATP. while cells like red blood cells have few mitochondria |
| compare and contrast anaerobic and aerobic respiration | Aerobic required oxygen and produces more ATP while anaerobic does not require oxygen and produces less ATP |
| how do anaerobic and aerobic solve the same problem? | They both break down glucose to create ATP |
| How do anaerobic and aerobic differ in energy production? | Anaerobic produces less ATP while anaerobic produces more |
