NADH transports electrons to what pump?
1
FADH2 transports electrons to what pump?
2
An ET Chain carries electrons to what pump?
2 and 3
An ET Chain carries electrons to what pump?
2 and 3
What is the final electron acceptor?
Oxygen
What powers the proton pumps?
Energy from electrons
What forms a gradient in the inner membrane space?
Protons from the matrix
Where do protons flow? (Chemiomosis)
ATP Synthase
Why are less than 36 ATPs made in respiration?
Mitochondrial membranes leak some protons
Why do we need a method to categorize and name organisms?
- Allows scientists to communicate precisely
- Provides a method to show relationships between organisms
What do similar features allow us to do?
- Group Organisms together
- Infer common ancestry
Homology
Similarities due to common ancestry
Analogy
Similarities due to a common type
Which is more useful—Homology or Anaoology?
Homology
