Enzymes are important biological catalysts because they: Lower the activation energy of a biochemical reaction Lower the entropy of a biochemical reaction Increase the free energy of a biochemical reaction Supply the energy to initiate a biochemical reaction

Define anabolism. How does anabolism relate to energy? What role does anabolism play in YOUR body? DO NOT JUST COPY AND PASTE PLEASE.

Match the letters with the following uncatalyzed  products  free energy  progress of reaction  catalyzed reaction  activation energy without an enzyme net change in energy between reactants and products reactants  activation energy with an energy

Enzymes will   Question 29 options:   lower the free energy of a reaction   raise the activation energy of a reaction   raise the free energy of a reaction   lower the activation energy of a reaction

Enzymes speed up a reaction by: Select one: a. Decreasing the amount of activation energy needed to drive the reaction b. Change the amount of energy of the reactant c. Increasing the amount of activation energy needed to drive the reaction d. Change the amount of energy of the products

The energy in organic molecules is released in a series of steps rather than a single step because: the amount of energy released would be too much to capture in one reaction. more total energy is released in multiple steps than would be released in a single step. less total energy is released in multiple steps than would be released in a single step. it is not possible to release it in a single step. only a single electron can be moved at a time in a cellular reaction. Incorrect

consider the active site of an enzyme. which of the following amino acids are likely to catalyze the reaction? choices A- Aspartate B-Alanine C- Valine

What does it require for the necessary reactions to occur if there is the absence of enzymes? choices: higher temp, larger cells, smaller atoms, larger proteins

Describe how an enzyme and substrate combine to facilitate a reaction.
