Why do chemical reactions occur faster at higher temperatures?   refers to enzymes.

How do cells keep chemical reactions from reaching equilibrium?   Question 22 options:   They use enzymes to force chemical reactions to happen   None of these   They use the products of chemical reactions as the reactants of other reactions or remove them from the cell   They use ATP to drive chemical reactions

Enzymes are:  [Select all that apply.] -waste products from the chemical reactions they catalyze. -molecules that are a main source of energy for most cells. -molecules that have specific shape that bind specific molecules. -mostly proteins. -molecules that catalyze (speed up) other chemical reactions. -waste products from most cellular chemical reactions.

Why does the product of each chemical reaction contain less energy than the starting substrate? Fuel substrates gain energy during metabolism. The product of the reaction contains more bonds. Chemical reactions are always anabolic. The product of the reaction contains fewer bonds.

Many enzymes help in cellular respiration. Using the figure to the right, explain the difference between this reaction with and without an enzyme. You must use the following terms in your answer; active site, induced fit, substrate and activation 1. Enzyme Action Without enzyme Activation energy without enzyme energy. With enzyme Activation energy with enzyme Reactants: Glucose + 0, Overall energy released during reaction Products: co, + H,0 Do NOT answer both questions 2 and 3. Choose only ONE to answer in the space provided. 2. The enzyme catalase is a polypeptide. Would you expect this enzyme to move through the cell membrane via simple diffusion? Explain your answer and provide a possible solution if catalase can't move across a membrane. 3. It is important for humans to make sure they consume small amounts of minerals (e.g. magnesium oxide or zinc oxide) in their food or in a supplement of some sort. Explain the value that some minerals play in assisting with many of our body's…

Classify each phrase as describing an enzyme, an active site, or a substrate. Enzyme may be a phosphate group a protein containing an active site a substance that the enzyme acts upon a biological catalyst Active site Answer Bank Substrate a specific enzyme location that binds with the substrate

Different enzymes are secreted in each of the three locations. Enzyme Location Temperature (°C) pH ptyalin mouth 36.7-37.0 6.5-7.0 pepsin stomach 37.3-37.6 1.0-3.0 trypsin small intestine 37.3-37.6 7.5-9.0 • Using the pH column in the chart, explain why pepsin can work in the stomach, but not the small intestines. State how a fever of 40°C would most likely affect the activity of these enzymes and support your answer using information from the temperature column in the chart. 27°F

what happens in a chemical reaction?  what does activation energy (EA) mean?

What is the item labeled "C" in the above figure?   The reactant   The substrate   The active site   The transition state   The product

Which type of chemical reaction, if any, occurs faster atequilibrium: the formation of products from reactants orthat of reactants from products?
