4ATP, 2GTP


Which products provide energy for the dark reaction and calvins cycle?

The nitrogen base tri-phosphates (like ATP, GTP etc) and NADPH produced during the Light reaction provide the energy for the Dark reaction.


Does chondriana reverse the aging process?

No. Condriana is a dormant part of your immune-system. It needs high ATP/GTP levels to become active. ATP/GTP on the other hand will reverse aging of cells.


In addition to ATP what types of molecules are produced in the kerbs cycle?

Gtp,nadh2,fadh2,co2


What is the major functional difference between the succinyl CoA-synthetase of plant and animal cell mitochondria?

Plant and microbial enzyme uses ATP, but animal enzyme uses GTP


Why is the GTP produced by the citric acid cycle energetically equivalent to ATP in metabolism?

GTP produced by the citric acid cycle energetically equivalent to ATP in metabolism because both ATP and GTP contain 3 phosphate groups and adenine and guanine are both the same type of nucleic acid. Moreover, they have very similar in its structure and energetic properties with each others


How many ATP's are produced during the Kreb's cycle?

The Krebs Cycle does not directly produce ATP (unless in bacteria, which produces 1 ATP instead of GTP).One cycle produces 3 NADH, 1 FADH2 and 1 GTP, which converts to 12 ATP.The Krebs Cycle produces 24 ATP per glucose molecule.


How many GTP molecules are produced during glycolysis?

Glycolysis only produces ATP. GTP is produced during the Citric Acid Cycle (Krebs Cycle).


Do enzymes change shape after a reaction occurs?

While the structure of an enzyme can, and often does, change over the course of a reaction, after a reaction has completed, enzymes are returned to their starting state. It is worth noting that certain cofactors (such as ATP or GTP) may also need to be replaced in order for the reaction to procede again.


How much ATP is made by the citric acid cycle?

http://library.thinkquest.org/C004535/media/kreb_cycle.gif Each round of the citric acid cycle produces one ATP. This as made as GTP, but this is quickly converted to ATP.


What two chemical compounds are used to store energy for Cells?

Atp, Gtp, Utp, Cellulose and Glycogen for starts.


What phase of cellular respiration does not produce ATP directly?

The Krebs cycle does not directly produce ATP. It produces NADH, FADH2, and GTP. All of which can be used to make ATP.
