How do organisms obtain energy?
From food or directly from the sun
Drinking a lot of water daily
Why do most organisms undergo cellular respiration?
They don't actually need to undergo cellular respiration
The cell needs to obtain energy to carry our their reactions and tasks
How do cells release energy from food in the presence of oxygen?
Fermentation
Aerobic Respiration
How do cells release energy from food without oxygen?
What is the Krebs Cycle
The Krebs cycle is the second stage of cellular respiration. Pyruvic acid is passed on to it from the first stage
The Krebs cycle is the first stage of cellular respiration where glucose is broken down
Which of the following is not an aerobic process?
Krebs Cycle
Glycolysis
Fermentation is an anaerobic process.
What is the difference between NADH and FADH2?
They aren't different
NADH is a high energy molecule and makes ATP. FADH2 carries the energy.
There is no difference between photosynthesis and cellular respiration.
How does a cell use potential energy from charge differences as a result of electron transport?
Chemiosmosis
ATP
Why is cellular respiration important for exercise?
If you didnt have cellular respiration you wouldnt be able to exercise at all
ATP cannot last if you exercise longer than 90 seconds
The matrix is the innermost part of the mitochondria.
How do organisms generate energy when there is no oxygen?
Glycolysis alone
Stores of ATP lasts for hours.
Fermentation is bad
