Question #5c115
1 Answer
Glycolysis is needed to produce Pyruvate and energy.
Explanation:
Glycolysis is the process in which glucose is broken down from its 6 carbon state into two three carbon molecules called Pyruvate or Pyruvic Acid. During this process 2 ATP is made into 2 ADP + 2 Pi (inorganic phosphate) to give energy for the process to occur. At the end of the process 4 ATP is made therefore you have made a net gain of 2 ATP molecules which are used as energy. 2 hydrogen are also taken away to the ETC to be used they are taken by hydrogen acceptors called NAD+
Glycolysis is anaerobic and does not need oxygen to occur where as the Krebs cycle and electron transport chain do.
The electron transport chain can make what is said to be 36 ATP per 1 molecule of glucose but it is generally lower. The electron transport chain makes the most amount of energy in the entire respiration process. The electron transport chain also produces water at the end as the hydrogen ions that are being pushed through out of the membrane through osmosis bind with OH- ions to create water, Glycolysis does not produce water.
The ETC occurs in the membrane of the mitochondria where as Glycolysis occurs in the cytoplasm.
I hope this helps and I apologise if I didn't make enough different points and if I rambled a bit.
