Name the two electron carriers of cellular respiration.
NAD and FAD
What steps use substrate-level phosphorylation?
glycolysis and krebs cycle/citric acid cycle
What is the difference between reduction and oxidation?
reduction-gain of electrons
oxidation-loss of electrons
What steps use oxidative phosphorylation?
ETC and Chemiosmosis
What is the difference between an oxidizing agent and reducing agent?
reducing agent-donate/loses electrons
oxidizing agent-accepts/gains electrons
Substrate-level: 2 ATP
Oxidative: 23-26ATP
Name the inputs and outputs of glycolysis.
Inputs: glucose, NAD+
Outputs: pyruvate, ATP, NADH
In what step of cellular respiration does oxygen go in to?
ETC
Name the steps of cellular respiration.
glycolysis, pyruvate oxidation, krebs cycle, oxidative phosphorylation
oxidized-NAD+
reduced-NADH
Name the inputs and outputs of pyruvate oxidation.
Inputs: pyruvate
Outputs: acetyl-CoA, NADH, CO2
What process occurs whether or not oxygen is present?
glycolysis
Name the inputs and outputs of the Krebs cycle.
Inputs: acetyl-CoA
Outputs: NADH, FADH2, ATP, CO2
Name the following steps:
- takes in O2
-releases CO2
takes in O2- oxidative phosphorylation (ETC/Chemiosmosis)
releases CO2- Krebs cycle, pyruvate oxidation
In the equation below, what is being reduced and oxidized?
C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
oxidized- glucose (C6H12O6)
reduced-O2
In what steps can an oxidized and/or reduced form on NAD be found?
all steps of cellular respiration
and fermentation
Name the inputs and outputs of oxidative phosphorylation.
Outputs-H2O, NAD+, FAD, ATP
What is the goal of fermentation? is this reduction or oxidation?
to regenerate NAD+ for glycolysis
oxidation because NADH to NAD+
Name the inputs and outputs of fermentation.
Input-pyruvate, NADH
Output-NAD+, ATP, CO2, lactate/ethanol
DAILY DOUBLE
What is the purpose of cellular respiration?
- creates ATP for the cells so they can function
For 1 glucose molecule that goes into the glycolysis, how many pyruvate, NADH, and ATP are made?
2 pyruvate
2 Net ATP
2 NADH
Name the final electron acceptors for the following:
-aerobic respiration
-alcohol fermentation
- lactic acid fermentation
- anaerobic respiration
aerobic-O2
alcohol-acetyldehyde
lactic acid-pyruvate
anaerobic-Not O2
it can either become acetyl-CoA if O2 present and go to krebs cycle
OR
it can become NAD+ if NO O2 and go to fermentation
Name the locations of each step of cellular respiration.
glycolysis- cytoplasm
pyruvate oxidation- matrix/cytoplasm
krebs cycle-matrix
oxidative phosphorylation-cristae/inner membrane
If 3 acetyl-CoA molecules entered the Krebs cycle, how many ATP, CO2, NADH, and FADH2 would be produced?
3 ATP, 6 CO2, 9 NADH, 3 FADH2
Remember for 1 acetyl-CoA you get:
1 ATP, 2 CO2, 3 NADH, 1 FADH2
