ATP and NADH from food are converted to CO2 and O2. NADH from glycolysis is converted to ATP and O2 molecules. Glucose is broken down in a cycle of reactions to form pyruvate. Pyruvate is broken down in a series of reactions to form CO2.
Sorry, this answer will be really long, so it will be very hard to find the answer but don't worry! I'll help you!
During the Krebs cycle... -The pyruvates produced in glycolysis are converted to Acetyl CoA molecules, which enter the Krebs cycle. -Acetyl-CoA combines with a four-carbon compound, forming a six-carbon compound and releasing CoA. -CO2 (carbon dioxide) is released from the compound, making a five carbon compound. Electrons are transferred to NAD+, making NADH. - CO2 is released from the five-carbon compound, making a four-carbon compound. One molecule of ATP is made, as is a molecule of NADH. -The four-carbon compound is converted into a new four-carbon compound; electrons are transferred to FAD, making FADH2. -The four-carbon compound is converted to the original compound that started the cycle. Another molecule of NADH is produced. Overall, NADH and FADH2 are the electron carriers that have all the high energy electrons, ready to be donated in the next step of cell respiration. 2 ATP molecules are produced, and carbon dioxide was released. Next, the electrons carried by NADH and FADH2 go through something called the electron transport chain; the electrons are donated through a chain, where they lose energy through every molecule it passes through. The energy is used to power hydrogen ions OUT of the mitochondria's inner compartments; this creates a concentration gradient, where the H+ ions diffuse back in. By diffusing back in, the carrier protein that it diffuses through makes ATP. On average, ETC makes 32 ATP. When the electrons are used up, they bind with hydrogen ions and oxygen molecules. This results in water- H2O. Oxygen is the final electron acceptor, and water is a waste product.
wait so whidh do u think it is?
I think its the first one. (A)
Why do you keep giving medals to me? I should return the favor! XD
Lolz thanks n it's the only way 2 show u that im so happy ur helpin me
cool! (Let me know if you need any help, otherwise I will retire to me Geometry work.)
i need more help on like 5 more
post the questions.
lol i did
