Q

Name and summarize 4 major stages of aerobic respiration.

A

glycolysis - the splitting sugar

pyruvate oxidation - when oxygen is available pyruvate enters the matrix of the mitochondria and then converts into acetyl CoA

kreb cycle
Converting a four carbon string molecule and combining it with aceta a to reduce NAD+ FAD+ ADP to 3 NADH and 1 FADH2 and 1 ATP her one term of the crib cycle

Electron Transport chain used NADH and FADH2 as electron transporters which allows chemo osmosis to occur and the production of ATP through the ATP synthase.

25
What is acetylene co-A and to what does it combine to?
Acetylene cove is the result of two pyruvate and a combining in private pro oxidation, which is then utilized in the crib cycle when it bonds to the four carbon molecule
26
what is the difference between oxidative phosphorylation and substrate level phosphorylation
oxadative phosphorylation is a result of passive like chemosomsis and ETC Substrate level phosphorylation is based on active from an enzyme like krebs and gylcolsis
27
49 What do molecules make up starting/ending molecule of the kreb cycle?
acetyl CoA and four carbon starting molecule
28
what three energy molecules are produced during cellular respiration
ATP NADH FADH2
29
Glycolysis spray down what molecule the form two molecules what are they?
Glucose breaks down into two pyruvate
30
what two molecules are used in the electron transport train to create ATP
NADH. FADH2
31
Why is ATP so important?
only energy our cells can use
32
NADH gets oxidized to form
NAD+ e- H+
33
Enzymes break apart FADH2 to form
FAD+ e- 2H+
34
what did the electrons do?
Get past along to the electron carriers and go down the electoral transport chain, as well as create a concentration gradient with thakoid membrane
35
what are the electrons main function in cellular, respiration and photosynthesis?
Help pump hydrogen into membrane space and create a proton gradient
36
Why is O2 needed for cellular respiration?
it is the final electron acceptor
37
why is H2O a product of cellular respiration?
Oxygen accepts electrons and grabs hydrogen to form water and that’s why we breathe out water
38
how does the chemo osmotic gradient help create ATP to form ADP
All the hydrogen want to get into the matrix with a lower concentration and can only get in through the ATP synthesis to produce the ATP
39
Why does the electron become excited in photos system one and photo system two
Photons of light absorbed
40
what happens to the electron in photo system two
Gets excited by the light energy and goes through the electron transport train
41
Where is the electrons final destination in light dependent reactions?
NADP+ to form NADPH
42
What happens to the hydrogen in the light dependent reactions?
Pumped across membrane from stroma to thylakoid space
43
How does the chemo osmotic gradient? Create ATP and ATP
Uses the energy of the hydrogen flowing through ATP synthesis to phosphorite ATP and P to ATP
44
What energy molecule is produced because of photosystem one
NADPH
45
why is H2O needed for photosynthesis?
Waters electrons will replace electrons loss in photosystem two this process is called photolysis

insufficient amount of which gas would result in the backup of lactic acid in muscle cells

what are the total number of ATP producing glycolysis?
4 ATP total 2 net
65
What would happen if there were no oxygen to act as the final electron acceptor?
NADH and FADH2 release their electrons in the system which shut down
