I'm sure a lot of ya'll are struggling with BIO so heres the answers for U3 L9 if u need them or if you're just checking your answers :)
1. Cellular respiration is an exothermic reaction and photosynthesis is an endothermic reaction. How does the required activation energy compare for these two reactions?
CORRECT ANSWER: Cellular respiration needs a smaller amount of energy to activate the reaction because the products are at a lower energy state than the reactants
2. How do enzymes affect chemical reactions?
CORRECT ANSWER: They lower activation energy
3. Which lists the correct order of steps involved in the formation of an enzyme-substrate complex?
CORRECT ANSWER: Enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place
4. Protease is an enzyme in the human body that catalyzes a chemical reaction in which proteins are broken down into smaller molecules so that the body can use them. Which is a likely outcome if protease does not function properly?
CORRECT ANSWER: The chemical reaction will not occur, and the body will not be able to absorb the protein it needs.
5. How does temperature affect enzyme activity in a chemical reaction?
CORRECT ANSWER: The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temp gets too high.
Hope this helps!!
