CH: 5 Cellular Respiration Flashcards
What process is the most basic form of energy creation: (used by all organisms, but for bacteria, it is the main process for energy)
Glycolysis
What does Glycolysis need to get the process started?
It needs ATP to break glucose into 3 carbon molecules
What does Glycolysis create?
ADP (originally to break down carbons) but then creates ATP, NADH and pyruvate.
Where does Glycolysis Occur?
In the cytoplasm or cytosol.
What are the two terms for the space outside the mitochondrion?
Cytosol or Cytoplasm
What is anaerobic vs. aerobic?
anaerobic - dosen’t require oxygen
Aerobic - requires oxygen
Where is NADPH and NADH found?
NADPH - plants
NADH - Non-plants
P for PLANTS
Is glycolysis aerobic or anaerobic
Glycolysis is anaerobic
How many pyruvates does glycolysis make?
2
Where does Krebs cycle preparation occur?
It occurs from the cytosol(cytoplasm) on the way to the mitochondrion
What carries the pyruvate to the mitochondrion? (Kreb cycle prep)
The CoA enzyme.
what does Glycolysis do?
Breaks down the glucose into pyruvate creating some ADP & ATP and NADH in the process
What are the four steps in cellular respiration?
- Glycolysis
- Krebs cycle prep
- Krebs cycle
- Electron transport chain
What are the starting and ending molecules in Krebs cycle preparation?
Pyruvate and CoA enzyme and NAD+ become acetyl CoA, carbon dioxide, and NADH
What transfers the molecules from the cytosol to the mitochondrion?
CoA Enzyme
What does the CoA enzyme do other than transport the molecules?
Converts NAD+ to NADH and combines with pyruvate to produce acetyl CoA and carbon dioxide.
How many times does the Krebs cycle prep have to happen in order to break down a glucose molecule?
Twice because of the two pyruvates glycolysis produces.
What does the Krebs cycle do?
Breaks down the remaining acetyl CoA into carbon dioxide, ATP, NADH, and FADH2
What is the first step of the Krebs cycle?
Acetyl CoA combines with a four-carbon molecule
What do the two carbons in acetyl CoA become in the Krebs Cycle?
Carbon Dioxide
what are Products from Krebs Cycle?
NADH, ATP, FADH2, CO2
How many times does the Krebs cycle have to happen in order to break down a glucose molecule?
Twice because of the two acetyl CoA Krebs cycle prep produces.
Where does the Krebs Cycle Occur?
In the Matrix inside of a Mitochondrion.
What gas is created in the Krebs Cycle?
Carbon Dioxide
