Steps
When oxygen is available, the pyruvate produced during glycolysis moves into the matrix of the mitochondria, where it undergoes an oxidation reaction, where carbon dioxide is released and NADH and aceytl-CoA are produced
What is pyruvate oxidation?
GDP forms GTP after a phosphate molecule replaces the CoA in succinyl-CoA. This creates this molecule
What is succinate?
The enzyme that helps change aceytl-CoA and oxaloacetate into citrate
What is citrate synthase?
In step 5, the GTP formed transfers its phosphate to ADP to form this molecule
What is ATP?
DAILY DOUBLE
The Krebs Cycle was first identified by this German physician and biochemist in 1937
Who is Sir Hans Adolf Krebs?
It is the product acetyl-CoA and oxaloacetate
What is citrate?
It oxidizes succinate to form FADH2 and fumarate
What is FAD?
An isomerase that changes citrate into isocitrate
What is aconitase?
This molecule is produced in the third and fourth steps of the Krebs cycle
What is carbon dioxide (CO2)?
The Krebs Cycle takes place in this part of the cell
What is the mitochondria?
Citrate is reconfigurated to form this molecule
What is isocitrate?
Water is added to fumarate to form this molecule
What is malate?
The enzyme that changes succinate into fumarate
What is succinate dehydrogenase?
This molecule is produced when NAD+ oxidizes isocitrate in the third step,
What is NADH?
Another name for the Krebs Cycle. This substance can be found in foods such as oranges and lemons
What is the citric acid cycle?
It is formed from NAD+ oxidizing isocitrate to form oxalosuccinate intermediate, which immediately loses CO2
What is
Another NAD+ oxidizes malate to form NADH and this molecule. It is then ready to combine with another acetyl-CoA entering the cycle
What is oxaloacetate?
DAILY DOUBLE:
The enzyme that changes fumarate into malate
What is fumarase?
This molecule is one of the products of pyruvate oxidation and the first molecule that is present in the Krebs cycle
What is aceytl-CoA?
The Krebs Cycle is the third step in this biological process
What is cellular respiration?
NAD+ loses another CO2 and combines with coenzyme A to form this molecule
What is succinyl-CoA?
The net production for each for each molecule of acetyl-CoA
What is 3 NADH, 1 FADH2, 1 ATP?
The enzyme that changes malate into oxaloacetate?
What is malate dehydrogenase?
The most important biological molecule is present in the Krebs cycle during steps 1 and 7
What is water (H2O)?
Although the use of oxygen is not directly involved in the Krebs cycle, it is considered this kind of process
What is aerobic process?
