Name the 5 steps in cellular respiration? (Assume plent of oxygen)
|
1. Glycolysis
2. Transition 3. Krebs Cycle 1 4. Krebs Cycle 2 5. Electron Transport System |
|
Where does the Electron Transport Chain take place?
|
Mitochondria
|
|
What 2 products are formed at glycolysis?
|
Carbon Dioxide (2)
NADH (2) |
|
Define Glycolysis
|
Break down of glucose to pyruvic acid
|
|
How many net ATPs are formed from glycolysis?
|
2
|
|
What products are formed from glycolysis?
|
2 NADH
2 ATP (net gain) 2 Carbon Dioxide |
|
What is catabolism?
|
Break down reactions (protein --> amino acids)
|
|
What is anabolism?
|
Small molecules bonded together to create larger molecules
|
|
What are 3 factors that affect metabolism?
|
Age, gender, hormones
|
|
5 reasons we need energy?
|
Muscle contraction, create chemical bonds, heat, active transport, cell division
|
|
What does a body need for energy? (6 things)
|
1. Oxygen
2. Calories 3. Mitochondria 4. Enzymes 5. Optimum temp 6. Optimum pH |
|
What happens during transition?
|
Pyruvic Acid turns to Acetyl CoA and releases carbon dioxide, NAD+ picks up 1 hydrogen from each pyruvic acid to form NADH+
|
|
What specifically does insulin do?
|
Allows glucose to enter cells from capillaries
|
|
True or False: Glycolysis is reversible
|
True
|
|
What products are formed by each turn of the Krebs Cycle?
|
3 NADH
1 FADH2 1 ATP 3 Carbon Dioxide |
|
Which part of cellular respiration is anaerobic?
|
Krebs Cycle
|
|
What is beta oxidation?
|
Fatty Acids turning into Acetyl CoA
|
|
What products does beta oxidation yield?
|
NADH+ and FADH+
|
|
How many ATP does beta oxidation produce?
|
COSTS one!
|
|
What is ketogenesis?
|
Liver converts acetyl CoA to ketones, which are released into the blood
|
|
Expain transamination
|
A number of amino acids transfer their amine group to a different acid (which becomes glutamic acid) and becomes a keto acid from the Krebs Cycle for further catabolism
|
|
Explain oxidative deamination
|
Glutamic acid from transamination is removed as ammonia and urinated out
|
|
Explain keto acid modification
|
The keto acid from transamination are processed in the Krebs Cycle, or for the case of the keto acid pyruvic acid being formed, it may be reversed back to glucose
