ATP & ENERGY
This molecule is the primary energy carrier in cells.
What is ATP?
True or False: Enzymes are used up during reactions.
False
Where does glycolysis occur?
What is the cytoplasm?
True or False: The Krebs Cycle occurs in the cytoplasm.
False.
True or False: The Electron Transport Chain is the first stage of cellular respiration.
False
This type of reaction releases energy.
What is an exergonic reaction?
These molecules speed up chemical reactions.
What are enzymes?
Does glycolysis require oxygen?
The Krebs Cycle occurs in this organelle.
What is the mitochondrion?
Where is the Electron Transport Chain located?
What is the inner mitochondrial membrane?
This is the energy needed to start a chemical reaction.
What is activation energy?
What is the main purpose of cellular metabolism?
To produce energy and support cell functions.
What molecule enters glycolysis?
What is glucose?
What important energy-carrying molecules are produced during the Krebs Cycle?
NADH and FADHâ‚‚.
What are the products of the Electron Transport Chain?
What are ATP and water?
Which stage produces the greatest amount of ATP?
What is the electron transport chain?
How do enzymes help reactions occur more quickly?
They lower activation energy.
What are the two main products of glycolysis?
ATP and 2 pyruvate.
Where does the Krebs Cycle occur?
What is the mitochondrial matrix?
Why is the Electron Transport Chain important?
It produces the majority of the cell's ATP.
When ATP loses a phosphate group, what happens?
Energy is released.
Why are enzymes important for living organisms?
They speed up essential chemical reactions.
Why is glycolysis considered the first stage of respiration?
It begins glucose breakdown.
What is the primary role of the Krebs Cycle?
To produce electron carriers for the ETC.
What is the final electron acceptor in the Electron Transport Chain?
What is oxygen?
