|
Know what happens in pyruvate oxidation
|
Pyruvate (3c) becomes acetyl CoA. we release a CO2
|
|
|
Be able to describe what products are created from this reaction
|
CO2 molecule and NADH, oxidation/reduction reaction.
|
|
|
Know the starting reactants of the citric acid cycle
|
Acetyl CoA and oxaloacetate
|
|
|
Know which steps create energy storage molecules (NADH, FADH2, ATP/GTP)
|
NADH gets made at step 3 step 4 and step 8
FADH2 gets made at step 6 GTP gets made at step 5 |
|
|
Know which steps create C02
|
3 & 4 |
|
|
Know why it is considered a cycle
|
Because what we end with starts it all over again.
|
|
|
Know how NADH and FADH2 help establish the Hydrogen ion concentration gradient
|
NADH and FADH2 donate their H and an electron to create ATP
|
|
|
Know what role electrons play in the electron transport chain.
|
Electrons provide energy to open the protein channels so H can go through.
|
|
|
know how many H+ are needed to make 1 ATP
|
3 |
|
|
Know where the water is generated from in ATP synthesis
|
Water is created from the H’s as they cross back through the plasma membrane and join with O2
|
|
|
Know some factors that can affect how many ATP are generated by cellular respiration
|
Organisms don’t always start with glucose and sometimes the process gets stopped part way through. 32-38
|
|
|
Know what it means that cellular respiration is aerobic respiration
|
It has oxygen to happen
|
|
|
Know what is means for respiration to anaerobic?
|
Doesn’t have oxygen inside the cells to do respiration
|
|
|
What does fermentation means occurs chemically?
|
What cells do when they don’t have oxygen. Like anaerobic respiration.
|
|
|
Where does the lactic acid in lactic acid fermentation come from?
|
Lactic acid comes from pyruvate at the end of glycolysis
|
|
|
What part of cellular respiration occur in lactic acid fermentation?
|
Only glycolysis
|
|
|
How much energy is produced in one cycle of lactic acid fermentation?
|
2 atp 2 nadh but we use the nadh’s to make galactic acid
|
|
|
What products does alcohol fermentation create?
|
Ethyl alcohol
|
|
|
How can the rate of cellular respiration be regulated?
|
Enzymes, they are either turned on or turned off, depending on if they’re activated or not
Competitive inhibition Allosteric inhibition Allosteric activation |
