Glycolysis
TRUE or FALSE
In the following equation
[CH4 (methane) + 2O2 --> CO2 + 2H 2O + energy]
methane is the oxidizing agent, while oxygen is the reducing agent.
Methane is the reducing agent and oxygen (O2) in the oxidizing agent.
Where does the citric acid cycle (Krebs cycle) occur in the mitochondria?
A) Cristae
B) outer membrane
C) matrix
matrix
TRUE or FALSE
During aerobic respiration, both NAD+ and FAD can donate electrons to the electron transport chain
False -
NADH and FADH2 can donate electrons to the electron transport chain
How many ATP molecules are produced during glycolysis for each glucose molecule used?
2 ATP
Before the citric acid cycle can begin, pyruvate must be converted into what molecule?
Acetyl CoA
In the electron transport chain, Electrons (e-) are passed to O2 to create H2O through a series of four protein complexes containing electron carriers called ___________?
cytochromes
Where does the glycolysis reaction occur in the cell?
cytosol
How many enzyme-catalyzed steps does the citric acid cycle have?
8 steps
The electron transport chain causes proteins to pump H+ ions (protons) from the mitochondrial matrix to the intermembrane space. Afterwards, H+ ions then moves back across membrane into the matrix through _____________ -->resulting in the majority of ATP production.
ATP synthase
What type of fermentation releases a CO2 molecule after glycolysis?
Alcohol fermentation
Daily Double!
What are the four products of the citric acid cycle?
CO2 , FADH2, NADH, ATP
Oxidative phosphorylation accounts for the majority of ATP production in cellular respiration. About how many ATP does this step produce from a single glucose molecule?
32- 34 ATP
(total reaction is 36- 38 ATP)
