Module 4 Flashcards
What molecule fuels the activity of our bodies?
ATP (from the food we eat)
What are the 3 major steps to aerobics metabolism?
Glycolysis, The Krebs cycle (AKA the citric acid cycle), and electron transport chain.
What are needed as inputs for cellular respiration?
Oxygen and Sugar.
What are the outputs for cellular respiration?
ATP, carbon dioxide, and water.
What is glycolysis and where does it take place?
It is glucose splitting and it happens in the cytoplasm.
What is needed for glycolysis to occur? (inputs)
Glucose
2 ATP
4 ADP
2 NAD+
What does glycolysis yield? (output)
2 Pyruvate*
2 NADH
4 ATP
2ADP
Where does the CAC (Krebs cycle) take place?
Matrix of mitochondria.
What are the inputs of the CAC?
Acetyl CoA (converted from pyruvate from glycolysis)*
NAD+
FAD
GDP
What are the outputs for CAC?
CO2
NADH*
FADH2*
GTP
Where does the electron transport chain take place?
Inner membrane of mitochondria.
What are the inputs of the electron transport chain?
NADH*
FADH2
O2
Pi and ADP
What are the outputs of the electron transport chain?
NADH+
FAD
H2O*
ATP
When a hydrogen ion gradient occurs related to aerobic metabolism how is ATP ultimately produced?
The energy taken away from the H+ passing through the transmembrane ATP synthase produces ATP.
What is the role of oxygen in the ETC?
No oxygen, no ETC.
