|
Know what happens in pyruvate oxidation occurs
|
Pyruvate becomes acetyl CoA
|
|
|
Be able to describe what products are created from this reaction
|
Releases a Co2 and NADH
|
|
|
Know the starting reactants of the citric acid cycle
|
Acetyl CoA and Oxaloacetate
|
|
|
Know what happened to each step of the cycle (drawing) |
Look at the picture! |
|
|
Know which steps create energy storage molecules (NADH,FADH2, ATP/GTP) |
NADH- Step 3, 4, & 8 FADH2- Step 6 GTP- Step 5 |
|
|
Know why it's considered a cycle |
Because the product at the end is also the start of the next cycle |
|
|
Know how NADH and FADAH2 help establish the hydrogen ion concentration gradient |
NADH and FADAH2 donate there hydrogen and electrons to create ATP |
|
|
Know what role electrons playing the electron transport chain |
Electrons provide energy to open the protein channel so hydrogen can pass through |
|
|
Be able to describe how electrons power the production of ATP and know how many H are needed to make one ATP |
There has to be 3 hydrogens to make 1 ATP |
|
|
Know where the water is generated from an ATP synthesis |
Water is created from the hydrogens as they cross back through the plasma membrane and join with oxygen(O2) |
|
|
No some factors that can affect how many ATP are generated by cellular respiration |
-32-38 -organisms don't always start with glucose and sometimes this process can get stopped partway through |
|
|
Know what it means that cellular respiration is aerobic respiration |
Has oxygen that it needs to happen |
|
|
Know what it means for respiration to anaerobic |
You don't have the oxygen in your cells |
|
|
What does fermentation means occurs chemically |
Fermentation is what cells do when they don't have oxygen "anaerobic" |
|
|
What does the lactic acid in lactic acid fermentation come from |
-Lactic acid comes from pyruvate at the end of glycolysis -lactic acid fermentation comes from glycolysis only |
|
|
How much energy is produced in one cycle of lactic acid fermentation. |
32-38 |
|
|
What products does alcohol fermentation create |
Ethanol |
|
|
How can the rate of cellular respiration be regulated |
We use enzymes |
