What is the purpose of the deamination process in the breakdown of proteins?
To remove the amino group from the carbon compound
Which stage of aerobic respiration occurs in the mitochondrial matrix?
Krebs cycle
What is the role of Acetyl CoA in aerobic respiration?
It enters the Krebs cycle
Which stage of aerobic respiration is responsible for the majority of ATP production?
Oxidative phosphorylation
What is the purpose of the link reaction in aerobic respiration?
To convert pyruvate into Acetyl CoA
How does the process of chemiosmosis contribute to ATP production in aerobic respiration?
It uses the energy released from the electron transport chain to pump protons across the inner mitochondrial membrane
Which process directly links chemiosmosis to the transport of ions across cell membranes?
Oxidative phosphorylation
What is the primary role of the Krebs cycle in cellular respiration?
To oxidize acetyl-CoA and generate NADH and FADH2
Which of the following is the primary source of electrons for the electron transport chain?
NADH and FADH2
Which process is directly coupled to the synthesis of ATP during oxidative phosphorylation?
Chemiosmosis
What is the primary function of acetyl-CoA in cellular respiration?
To serve as the entry point for the Krebs cycle
Which of the following is a direct product of the Krebs cycle?
NADH and FADH2
What is the purpose of the Krebs cycle in aerobic respiration?
To generate reduced coenzymes and release carbon dioxide
What is the role of acetyl-CoA in the Krebs cycle?
Acetyl-CoA combines with a four-carbon molecule to form a six-carbon molecule that enters the Krebs cycle
What is the purpose of the electron transport chain in oxidative phosphorylation?
To generate proton gradients across the inner mitochondrial membrane
What is the role of chemiosmosis in the production of ATP during oxidative phosphorylation?
Chemiosmosis is the movement of protons across the inner mitochondrial membrane, which is coupled to the synthesis of ATP
How many ATP molecules are directly produced in the Krebs cycle through substrate-level phosphorylation?
1 ATP
What is the final electron acceptor in the electron transport chain during oxidative phosphorylation?
Oxygen (O2)
