Cellular Respiration Flashcards
What is the formula for Cellular Respiration?
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Glucose + 6 Oxygen Gas → 6 carbon dioxide + 6 water + energy
Cellular respiration uses _ to produce ATP.
Glucose
Enumerate the three stages of Cellular Respiration mentioned in the book.
- Glycolysis
- Citric Acid Cycle (Krebs Cyle)
- Electron Transport Chain
Glycolysis takes place in the…
Cytoplasm
True or False.
Glycolysis is aerobic (requires oxygen).
False, Glycolysis is anaerobic (does NOT require oxygen)
One Glucose molecule can be broken down into _ molecules of _ .
One Glucose molecule can be broken down into two molecules of pyruvate.
Glycolysis produces…
2 ATP (energy), 2 NADH, and 2 pyruvate molecules.
This is the Aerobic stage of Cellular Respiration, or the stage that requires oxygen.
Citric Acid Cycle (Krebs Cycle)
This stage of Cellular Respiration occurs in the mitochondria.
Citric Acid Cycle (Krebs Cycle)
This stage of Cellular Respiration is aerobic (Requires Oxygen)
Citric Acid Cycle (Krebs Cycle)
In the Citric Acid Cycle,
Pyruvate from Glycolysis enters the _ and is converted into _
Mitochondria
Acetyl-CoA
Acetyl-CoA is oxidized, and then enters the…
Citric Acid Cycle
NADH and FADH₂ are _ carriers
Electron
Because of the oxidation process of Acetyl-CoA, _ _ _ are transferred to electron carriers: NADH and FADH₂.
High-energy electrons
What are the products of the Citric Acid Cycle (Krebs Cycle)
4 Carbon Dioxide
6 NADH
2 FADH₂
2 ATP
This takes place in the inner mitochondrial membrane. (Cellular Respiration)
Electron Transport Chain (ETC)
Electrons carried by NADH and FADH₂ are transported through a series of _ complexes in the inner mitochondrial membrane.
protein
As electrons move across the chain, they release energy, which is used to pump _ (H+), across the inner _ membrane, which creates an _ _.
protons
mitochondrial
electrochemical gradient
A proton gradient is used to drive the production of _, in a process called _ _.
ATP
Oxidative phosphorylation
ATP is produced in the Electron Transport Chain in a process called _ _.
Oxidative Phosphorylation
Many ATP is produced in which part of Cellular Respiration?
Electron Transport Chain
In terms of ATP generation, which of the following is correct?
a.) Krebs Cycle > Glycolysis > ETC
b.) Krebs Cycle < ETC < Glycolysis
c.) Glycolysis > Krebs Cycle > ETC
d.) Glycolysis < Krebs Cycle < ETC
d.) Glycolysis < Krebs Cycle < ETC
What does NADH stand for?
Nicotinamide Adenine Dinucleotide + Hydrogen
If it requires oxygen, it is…
Aerobic respiration
if it does not require oxygen, it is…
Anaerobic respiration
