Describe the formation of citric acid the first intermediate in the Krebs cycle?
Citric acid is formed in the Krebs cycle when oxaloacetate, a four-carbon compound, combines with acetyl-CoA, a two-carbon compound derived from pyruvate. This condensation reaction is catalyzed by the enzyme citrate synthase, resulting in the formation of citric acid as the first intermediate in the cycle.
In the Krebs cycle acetate combines with what 4-carbon compound?
oxaloacetic acid
What is the 3 carbon sugar that is formed when glucose is split in half during the krebs's cycle?
The 3-carbon sugar formed when glucose is split in half during the Krebs cycle is called pyruvate. Pyruvate is a key intermediate in cellular respiration and is further broken down to generate energy in the form of ATP.
What waste product formed during the Krebs cycle?
Carbon Dioxide is produced during the Kreb cycle (also called the citric acid cycle).
What is transported to the mitochondria to serve as a starting point for the Krebs cycle?
Pyruvate formed from the gylcolysis of glucose is actively transported into the matrix of the mitochondrian. Here it enters another stage know as the link reaction, whereby it is decarboxylated and dehydrogenated into a 2 carbon compound which binds with an enzyme known as Coenzyme A(CoA). This forms Acetyl Coenzyme A which is then used as the starting point in the Krebs cycle where it will join with a 4 carbon oxalacetate to from 6 carbon citrate.
In Krebs cycle a six carbon compound is formed how?
citrus acid
What is a waste product formed during the Krebs cycle?
carbon dioxide

In the Krebs cycle acetate combines with what 4-carbon compound?
oxaloacetic acid
What two molecules are lost in the Krebs cycle taking it from a six carbon compound to a five carbon compound to a four carbon compound?
Sodium and potasium

The 3-carbon sugar formed when glucose is split in half during the Krebs cycle is called pyruvate. Pyruvate is a key intermediate in cellular respiration and is further broken down to generate energy in the form of ATP.
What waste product formed during the Krebs cycle?
Carbon Dioxide is produced during the Kreb cycle (also called the citric acid cycle).
True or false The compound that joins with a 4-carbon molecule in the krebs cycle is called acetyl-CoA?
It is true that the compound that joins with a 4-carbon molecule in the krebs cycle is called acetyl-CoA. It is also known as Acetyl coenzyme A.
What substances are formed during Krebs cycle?
The Krebs cycle primarily generates ATP, carbon dioxide, and reduced electron carriers NADH and FADH2. These molecules are essential for energy production in the mitochondria.
What gas is in the Krebs cycle?
Carbon dioxide (CO2) is a byproduct of the Krebs cycle. It is produced during the decarboxylation reactions that occur within the cycle, where carbon atoms are removed from molecules like citric acid.
What is the series of reactions in aerobic respiration that begins and end with the same carbon compound?
Krebs cycle
Which one is formed during the Krebs cycle FADH2 or pyruvic acid?
FADH2 since pyruvic acid is needed to START the Krebs cycle
