Photosythesis And Cellular Respiration
| Question | Answer |
|---|---|
| Where does the reaction of Photosynthesis take place? | Chloroplasts |
| Where does the reaction of Cellular Respiration take place? | MItochondria |
| What is a Heterotroph? | An organism that obtains energy from the food they comsume. Examples: Most Animals, Humans |
| What is an autotroph? | Anorganism that make their own food by gettting energy from the sun. Examples: Plants, Some bacteria, and algee. |
| What is ATP? | Energy that can be stored and released in cells. |
| What are pigments? | Light absorbing molecules |
| What are the 3 things inside a Chloroplast? | Thykloids, Photosystems, and Stroma. |
| What is a thykloid? | Inside a chlorplast, arranged in stacks called grana, and light dependant reactions take place here. |
| What is the stroma? | Calvin Cycle takes place here, the space around the thykloid membranes |
| What is NADP+? | carrier molecules, can hold 2 high-energy electrons and a hydrogen ion (H+), this holding creates NADPH. |
| What does the calvin Cycle produce? | HIgh-energy Electrons |
| What are the reactants in the calvin cycle? | ATP and NADPH from light dependant reations. |
| What is a light dependant reaction? | A reaction that requires light |
| What are the product(s) of light dependant reactions? | oxygen gas |
| What are the three steps of Respiration? | Glycolysis, Krebs Cycle, Electron Transport Chain (if oxygen is present) |
| How many ATPs are produced during Respiration when oxygen is present? | 36 ATPs |
| What is glycolysis? | the process of breaking glucose in half making 6 carbon molecules into 3 carbon molecules called pyruvic acid. |
| What are the products in the Krebs Cycle? | carbon dioxide |
| What is the Electron transport chain? | uses high-energy electrons (from the Krebs Cycle) to convert ADP into ATP. |
| What are the wastes from cellular respiration? | low-energy electrons and hydrogen ions |
| How many ATPs are produced in glycolysis without oxygen? | 2 ATPs are produced per glucose |
| How many phosphate groups are on ADP? | 2 |
| What happens when a phosphate group in added on to ADP? | ATP is produced. |
| What is fermentation? | Glycolysis pathway when oxygen is not present, two types of |
| What are the two types of Fermentation? | Lacti Acid Fermentation, and Alcohloic Fermentation |
| What are the reactants in lactic acid fermentation? | pyruvic acid and NADH |
| What are the products in Alcoholic Fermentation? | alcohol, Carbon dioxide, and Nad+ |
| What are the reactants in Alcoholic Fermentation? | Pyruvic acid and NADH |
| What are the products in Lactic acid Fermentation? | Lactic Acid ad NAD+ |
| What is Lactic Acid? |
