Total questions: 22
Worksheet time: 22mins
If ADP is phosphorylated, then what is happening in the reaction?
ADP is combing with a phosphate to become ATP
ADP is becoming AMP
ADP is being used to power other reactions
ADP is being created by the reaction
Which of the following is one of the reactants of cellular respiration?
energy
glucose
carbon dioxide
water
What is the name of the first set of reactions in cellular respiration?
What is the main job of the electron carrier molecules (NADH and FADH2) in cellular respiration?
What enzyme (large spinning protein complex) connected to the ETC is responsible for generating the ATP molecules?
ATPase
ATP synthase
Hexokinase
Electron transport chain
Where is the electron transport chain of oxidative phosphorylation physically located?
Mitochondrial matrix
Outer mitochondrial membrane
Inner mitochondrial membrane
Cytosol
The final electron acceptor at the end of the electron transport chain is _______.
What is the main electron shuttle (carrier) molecule in cellular respiration?
ATP
NADH
ADP
Glucose
Typical reactions in glycolysis and the citric acid cycle remove electrons and H+ from _________________ and add them on to NAD+ to form ____________________.
glucose; NADH
oxygen; NADH
oxygen; ATP
glucose; ATP
Which phase of cellular respiration generates the majority of the ATP?
glycolysis
citric acid cycle
Kreb's cycle
ETC and oxidative phosphorylation
This diagram is showing the first few reactions of glycolysis. According to the diagram, what is happening to glucose?
It is being used to make 2 ATP molecules. Energy is being captured.
Phosphate groups from 2 ATP molecules are added to the glucose molecule. Energy is being invested.
The glucose is being oxidized.
The glucose is being reduced.
Why does the diagram say "happens twice" on the right hand side?
The initial glucose has two much energy to indicate in this diagram
The initial glucose was split in an earlier step. Each of the two molecules goes through the rest of the steps.
The four initial glucose molecules have been combine through enzyme catalyzed reactions to form two glucose molecules.
How many ATP and NADH are produced in this part of glycolysis?
2 ATP, 1 NADPH
4 ATP, 2 NADPH
Only ADP and NAD+ are produced
What part of cellular respiration is this diagram showing
Glycolysis
Citric acid cycle
Pyruvate oxidation
Oxidative phosphorylation
Based on the diagram, where is there a high concentration of H+ ions?
cytoplasm
cytosol
mitochondrial matrix
intermembrane space
Based on the diagram, would happen if the ATP synthase protein became impermeable to H+ because another molecule was blocking the H+ channel?
The cell would produce more ATP
The cell would produce less ATP
Glycolysis would stop working
The amount of ATP would not be affected because the ETC still functions.
