Question

Chemical bonds are broken and reformed in all chemical reactions. A reaction that results in the release of energy is referred to as Select one: a. Exergonic b. Dangerous c. Endergonic d. Activation e. Photosynthesis In lab, catalase will be used to initiate a particular chemical reaction that breaks hydrogen peroxide down into water and oxygen gas. Which is the substrate in this reaction? Select one: a. Hydrogen b. Catalase c. Hydrogen peroxide d. Water e. Oxygen gas The initial input of energy required to initiate any chemical reaction is called? Select one: a. Oxidation energy b. Activation energy c. Kinetic energy d. Active site energy e. Reduction energy The part of an enzyme that a substrate recognizes and eventually binds to is called Select one: a. Cofactor b. Active site c. Pyruvate d. Isomer e. none of these The synthesis of high energy glucose molecules from low energy molecules, carbon dioxide and water, requires a large input of solar energy and illustrates which type of reaction? Select one: a. Endergonic b. Hypotonic c. Hypertonic d. Exergonic e. none of these

Explanation / Answer

Question 1: The answer is
a. Exergonic

If it absorbs energy those are considered to be Endergonic

Question 2: The answer is
c. Hydrogen peroxide

The left side material of the chemical equation is the substrate

Question 3: The answer is
b. Activation energy

Question 4: The answer is
b. active site

Question 5: The answer is
a. endergonic

Photosynthesis is an example for Endergnoic where as Respiration is example for Exergnoic reactions.
