Chapter 8: Section 3 Flashcards
Energy
The ability to cause motion
Thermodynamics
Energy turns into heat
ATP
Made in atp synthase, ATP>ADP subtract a phosphate
Cellular energy
How organisms obtain energy
Equation for cellular respiration
Glucose+oxygen—> carbon dioxide+water+ATP
Glycolysis = _____
Sugar
Glucose
Sugar
Lysis
Breaking down
Why is mitochondria that powerhouse of the cell?
Because it makes energy (ATP)
In glycolysis you need:
Sugar, atp, nadp+
Process of glycolysis:
- Glucose is broken down in the cytoplasm through the process of glycolysis
- Two molecules of ATP are used to break down glucose
- Four ATP and two NADH is produced for each molecule of glucose that is broken down. End product is two Pyruvates
What needs to happen before glycolysis can continue
Pyruvate needs to be made
Krebs Cycle
Pyruvate releases co2 making NADH producing acetyl CoA. CoA bonds with the 4 carbon compound. Making 6 carbon (citric acid). Loses another co2 Making another NADH, becomes a 5 carbon. Loses another Co2 making NADH, becomes a 4 carbon. Then make FADH2. Charged with atp. Makes NADH. You are left with the 4 carbon compound that will continue the cycle.
Glycolysis has made a net of result of:
2 ATP, NADH, and 2 pyruvate
Aerobic
Needs oxygen
Final step of cellular respiration in the membrane
- Hydrogen from NADH release e-
- H+ are pumped outside matrix and accumulate and go through ATP synthase
- E- to membrane to travel down chain giving up energy to produce ATP
- Used e- is then reunited with P+ forming H
- Two H combine with O water is produced (H2O)
Why do we need oxygen?
Oxygen picks up hydrogen, allows the transport chain to run, makes ATP so we can continue to live
What makes the ATP?
Energy from the electron
ATP TOTALS:
Glycolysis
(2 ATP net) produces 4 ATP and 2 NADH
ATP TOTALS:
Krebs
2 ATP, 8NADH, 2FADH2
ATP TOTALS:
Electron transport
24 ATP from multiplying the 8NADH from the Krebs cycle x3
ATP TOTALS:
Extra info to know:
Each NADH = 2 ATP
Each group of 3 FADH2 = 2ATP (only 2 produced so not a factor figured into total below)
ATP TOTAL:
36 ATP from one molecule of glucose
Anaerobic
Anti oxygen
