Cellular Respiration Flashcards
Cellular Respiration
a process that combines glucose and oxygen to make ATP
Aerobic
Needs oxygen
Anaerobic
Doesn’t need oxygen
Reactants for Cellular Respiration Formula
Glucose (C6H12O6) + Oxygen
(6 O2)
Products for Cellular Respiration Formula
Water (6H2O) + Carbon Dioxide (CO2)
Indirect Product of Cellular Respiration
ATP
Where does cellular respiration occur?
All cells of the body
Where does glycolysis occur?
The cytoplasm of cells
Is glycolysis aerobic or anaerobic?
Anaerobic
Step 1 of glycolysis
Releasing the energy of glucose
Step 2 of glycolysis
Glucose is broken down into carbon molecules called pyruvate
Step 3 of glycolysis
NADH is made and they carry electrons from glucose to the next step
Is the Citric Acid Cycle (Krebs Cycle) aerobic or anaerobic?
Aerobic
Where does the Citric Acid Cycle (Krebs Cycle) occur?
The matrix of the mitochondrion
Step 1 of the Citric Acid Cycle (Krebs Cycle)
Pyruvate is converted and CO2 is made
Step 2 of the Citric Acid Cycle (Krebs Cycle)
NADH and FADH2 pick up electrons and shuttle them to the next step
How much ATP do Glycolysis and the Citric Acid cycle make?
2 each
What processes make up Oxidative Phosphorylation?
Electron Transport Chain & Chemiosmosis
Where does Oxidative Phosphorylation occur?
The inner membrane of the mitochondrion
How much ATP does Oxidative Phosphorylation make?
32-34 ATP
ETC does not…
Produce ATP
Chemiosmosis produces…
Most of the ATP from a one glucose molecule
What does biosynthesis mean?
Building for growth and repair
What polymers are made during biosynthesis?
Glycogen, muscle tissue, enzymes
