Energy and Entropy
The ability to do work or bring about a change.
What is energy?
The sum of cellular reactions in a cell.
What is metabolism?
The reactants of an enzymatically catalyzed reaction.
What are substrates?
Long term for redox reactions.
What are oxidation-reduction reactions?
(Weird format) What is significant about the equations of cellular respiration and photosynthesis compared?
They are opposite of each other.
Stored Energy
What is potential energy?
The energy available to perform work.
What is free energy?
The energy required to start a chemical reaction.
What is the activation energy?
Enzymes speed up reactions.
What is enzymes lower activation energy?
The main organelle involved in photosynthesis.
What is a chloroplast?
Living organisms depend on a constant supply of this.
What is solar energy?
High-energy compound used to drive metabolic reactions.
What is Adenosine Triphosphate (ATP)?
The term used to describe when the enzyme changes shape to fit the substrate.
What is the induced fit model?
The loss of an election and the gain of an electron.
What is oxidation and reduction?
The site of oxidation of glucose to make ATP.
What is mitochondria?
What is entropy?
This describes the products of one reaction being the reactants of another reaction.
What is a metabolic pathway?
The term describing what happens to enzymes when they are not at their optimum pH or temperature.
What is denaturation?
Inhibitor directly competes for the active site of an enzyme.
What is competitive inhibition.
Type of reaction cellular respiration and photosynthesis are.
What are redox reactions?
When energy changes forms, there
is a loss of energy that is available to do work.
What is the Second Law of Thermodynamics?
What is coupling?
Organic molecules that combine with an enzyme to facilitate a chemical reaction and are chemically changed in the reaction but are returned to their original state?
What are coenzymes?
What is an allosteric site?
One reason regarding metabolism why plants differ from animals.
What is plants go through photosynthesis and cellular respiration, while animals only go through cellular respiration?
