What molecule does Krebs Cycle begin with?
Acetyle Co-A + Oxaloacetate
What molecule is formed by the combination of oxaloacetate with acetyl CoA in the first step of the Krebs cycle?
citrate
How many water molecules produce in Krebs cycle?
Two: 1) oxaloacetate => citrate 2) fumarate => malate
What is starting molecule for Krebs cycle?
The Krebs cycle starts with acetyl CoA, and combines with oxaloacetate to form citrate, a six-carbon molecule. Citrate is further oxidized until oxaloacetate is again reached at the end to restart..
What is the main features of the Krebs cycle?
The Krebs cycle occurs in the matrix of the mitochondrion. It occurs only in aerobic conditions, that is, only when oxygen is present. Its main function is to oxidise acetyl CoA generated from glycolysis. In the Krebs cycle, acetyl CoA and oxaloacetate undergo a condensation reaction to form a six-carbon compound. Through a series of decarboxylation and dehydrogenation reactions, intermediate 5-carbon and 4-carbon compounds are formed with the release of carbon dioxide. 1 ATP molecule is generated per turn of the Krebs cycle by substrate level phosphorylation; hence 2 ATP molecules are formed per molecule of glucose. Most fo the chemical energy is transferred during the redox reactions where the electron carriers NAD and FAD are reduced to form coenzymes NADH and FADH2, respectively. The Krebs cycle is also cyclic as the starting product, oxaloacetate, is regenerated.
What four carbon compounds are regenerated at the end of the Krebs cycle?
Oxaloacetate
The "regenerator" of the Krebs Cycle is?
Oxaloacetate
What is oxaloacetat?
Oxaloacetate is an intermedier in the Krebs cycle
What molecule does Krebs Cycle begin with?
Acetyle Co-A + Oxaloacetate
What molecule is formed by the combination of oxaloacetate with acetyl CoA in the first step of the Krebs cycle?
citrate
The Kreb cycle starts with what?
The Krebs cycle starts with acetyl CoA, and combines with oxaloacetate to form citrate, a six-carbon molecule. Citrate is further oxidized until oxaloacetate is again reached at the end to restart the Krebs cycle.

If an organism is able to convert the sodium citrate?
Citrate, a Krebs cycle (i.e., TCA cycle or citric acid cycle) intermediate, is generated by many bacteria; however, utilization of exogenous citrate requires the presence of citrate transport proteins (permeases). Upon uptake by the cell, citrate is cleaved by citrate lyase to oxaloacetate and acetate. The oxaloacetate is then metabolized to pyruvate and CO2.

What compound that is derived from glucose actually enters the Krebs cycle?
Acetyl-Coenzyme A (Acetyl-CoA) is the compound the enters the Kreb's cycle and reacts with oxaloacetate. It is dervied from the pyruvate, produced in glycolysis, that has gone through decarboxylation and has conezyme A attached to it.
What molecule starts Krebs cycle?
Oxaloacetic acid = HO2C-CH2-CO-CO2H. By the Way the Correct name is "The Tri-carboxylic-acid cycle".
