The breakdown of glucose is
Adding electrons to another substance is known as
__________________ normally proceeds whether or not O2 is present.
The electron acceptor is known as the ______________ agent
The oxygen consumed in cellular respiration is directly involved in what other process during cellular respiration?
final acceptor of electron transport chain
What substances are produced in a muscle cell under anaerobic conditions?
Lactic Acid, 2 ATP, NAD+
What are the end products of glycolysis?
Net gain of 2 ATP and produces 2 NADPH and two pyruvate
What are the products of the Kreb's cycle?
6 CO2 , 2 FADH2, 2 ATP, 8 NADH
What molecule enters the Kreb's cycle that is formed by the removal of CO2 from a molecule of pyruvate?
Each time a molecule of glucose is completely oxidized via aerobic respiration, how many O2 molecules are required?
Which of the stages of cellular respiration is most closely associated with intracellular membranes?
electron transport chain (oxidative phosporylization)
What generates the proton gradient in the mitochondria?
Chemiosmosis, the H+ that are released in the electron transport chain
What is the proton gradient in the mitochondria primarily used for?
the energy is used to drive the phosphorylation and produce ATP
In cellular respiration, which stage produces the most ATP when glucose is completely oxidized to CO2 and H2O?
electron transport chain (chemiosmosis)
In cellular respiration, which one of the stages normally occurs whether or not oxygen is present?
Which one of the stages occurs in the cytosol of the cell?
glycolysis and fermentation
Carbon dioxide is release during which stages(s)?
krebs cycle [oxidation of pyruvate to acetyl CoA]
What must a muscle cell do to keep contracting (don't over think this)?
get oxygen. regenerate atp quickly
What carbon skeletons (think monomers and polymers) can be broken down during cellular respiration?
lipids, proteins, polysacharides
_____________ do(es) not participate in glycolysis.
You have a friend who lost 15 pounds of fat on a diet. Where did the fat go?
was broken down into energy that was used to make atp in cellular respiration, released as co2 and h20
How many moles of ATP are produced from the complete oxidation of a mole of glucose in cellular respiration?
