NO. You release 2 CO2 from each turn on the kreb cycle. You have to go around the cycle twice in order to decarboxylate 1 glucose molecule (you go around twice because you have 2 pyruvate molecules in one glucose, meaning one full turn of the kreb cycle per pyruvate molecule)

What most the Krebs cycle have that glycolysis doesnt require?
pyruvate
What breaks down pyruvate down into carbon dioxide?
Krebs cycle
What process occurs before the Krebs cycle?
The formation of acetyl-CoA
What goes into the pyruvate cell?
It is changed into Acetyl CoA, which is then used in the citric acid cycle (aka Krebs Cycle).
What is is the order of the steps for cellular respiration?
1. Glucose is metabolised to form pyruvate (glycolysis) Anaerobic (without oxygen): - Pyruvate is converted to lactate or ethanol Aerobic (in the presence of oxygen): - Pyruvate is converted to acetyl CoA - Citric Acid Cycle - Electron transport chain
What is the end result of glycolysis that eventually feeds into the Krebs cycle?
A. Glucose is broken down into two molecules of pyruvate Glucose is broken down into two molecules of pyruvate.
Which of the following is not a requirement for the Krebs Cycle?
Pyruvate
Before entering Krebs Cycle, pyruvate is?
Oxidized
What generally happens in the Krebs cycle?
In Krebs cycle, there’s the breakdown of a 2 carbon molecule called acetyl coA to release CO2 and generate energy (ATP). This video explains it best 🔥 “Krebs cycle @ Dr Hills Academy on YouTube”
What most the Krebs cycle have that glycolysis doesnt require?
pyruvate
What does one pyruvate produce after the Krebs cycle?
1 atp
What stage of cellular respiration pyruvate as a product?
the krebs cycle produces pyruvate as a product to be used by the ATP molecules.
What molecule moves into the Krebs cycle?
Pyruvate -> Acetyl CoA -> Citrate which is used by the Krebs or Citric Acid Cycle.
What breaks down pyruvate down into carbon dioxide?
Krebs cycle
What is the correct sequence of glycolysis electron transfer and Krebs?
Glycolysis->Krebs Cycle->Electron Transfer
Before Krebs cycle can proceed pyruvate must be converted into what?
Pyruvate is converted to acetyl-CoA before entering the Krebs cycle.
What happens to pyruvate molecules formed glycolysis in the absence of oxygen?
they will enter the Krebs cycle
