What molecules initiate the citric acid cycle by reacting with oxaloacetate?
Wiki User
∙ 13y ago
Oxaloacetate [oxaloacetic acid], under the strict guidance of the enzyme 'citrate synthase', is reacted with the co-enzyme 'Acetyl-CoA' to form the products CoA and citric acid.

What are the intermediates in the citric acid cycle?
There are 4: oxaloacetate, malate, fumarate, and succinate.
How many molecules are there in 192 g of citric acid C6H8O7?
molar mass citric acid = 72 + 8 + 112 = 192g/mol 192 g x 1 mol/192g x 6.02x10^23 molecules/mole = 6.02x10^23 molecules
Is tamarind is acidic or basic?
It is understood that tamarind contains mainly tartaric acid
How does pH affects the rate of browning?
The lower the pH, the more acidic a substance is. Citric acid is used to prevent apples from browning once they are cut. Therefore, an acid, low pH prevents browning. This is done by keeping oxygen from reacting with the apple with the barrier created by the citric acid.
Chemical equation for citric acid reacting with potassium hydroxide?
In three steps the exchange of the acid H+ions each to one added hydroxide ion OH-: (HOOC)3C3H5O4 + 3 OH- --> (-OOC)3C3H5O4 + 3H2O
Which of the following compounds is regenerated in the citric acid cycle?
Oxaloacetate
An immediate consequence of a cellular deficiency of oxaloacetate is a slowing of what?
An immediate consequence of a cellular deficiency of oxaloacetate is the slowing of the Citric Acid Cycle. The citric acid cycle is also called the tricarboxylic acid cycle.
What are the intermediates in the citric acid cycle?
There are 4: oxaloacetate, malate, fumarate, and succinate.
How are citric acid produced?
A Condensation reaction between oxaloacetate and acetyl CoA by the enzyme citrate synthase
Can fatty acids be converted to oxaloacetate?
Not directly. Fatty acid β-oxidation results in acetyl CoA, which is then entered to the Citric Acid cycle. The "last" step of the cycle is the formation of oxaloacetate from malate.
In the Krebs cycle what molecules acquires most of the energy that is released by the oxidation of acetyl CoA and how many of these molecules are produced during each turn if the cycle?
Krebs Cycle is also known as the Citric Acid Cycle. The citric acid cycle begins with acetyl-CoA transferring its two-carbon acetyl group to the four-carbon acceptor compound (oxaloacetate) to form a six-carbon compound (citrate). The citrate then goes through a series of chemical transformations, losing first one, then a second carboxyl group as CO2. The carbons lost as CO2 originate from what was oxaloacetate, not directly from acetyl-CoA. The carbons donated by acetyl-CoA become part of the oxaloacetate carbon backbone after the first turn of the citric acid cycle. Loss of the acetyl-CoA-donated carbons as CO2 requires several turns of the citric acid cycle. However, because of the role of the citric acid cycle in anabolism, they may not be lost since many TCA cycle intermediates are also used as precursors for the biosynthesis of other molecules.[4] Most of the energy made available by the oxidative steps of the cycle is transferred as energy-rich electrons to NAD+, forming NADH. For each acetyl group that enters the citric acid cycle, three molecules of NADH are produced. Electrons are also transferred to the electron acceptor FAD, forming FADH2. At the end of each cycle, the four-carbon oxaloacetate has been regenerated, and the cycle continues
What substance does the citric acid cycle break down?
The citric acid cycles converts citrate (produced from the combination of oxaloacetate and Acetyl Coenzyme A) back into oxaloacetate in a series of steps that will end up yielding 2 ATP, 3 NADH and 1 FADH2 per pyruvate. *4 NADH if you include the NADH produced from the creation of Acetyl Coenzyme A in the link reaction.
What compound is produced by the transfer of the acetyl group of acetyl CoA to oxaloacetate?
Citric acid or citrate. The reaction is catalyzed by the citrate synthase enzyme.
How do you combine baking soda with citric acid without it reacting?
Use a dry salt of citric acid - like sodium citrate. Add water. THEN they react.
How many molecules are there in 192 g of citric acid C6H8O7?
molar mass citric acid = 72 + 8 + 112 = 192g/mol 192 g x 1 mol/192g x 6.02x10^23 molecules/mole = 6.02x10^23 molecules
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.
Why does lemon juice make metals rust?
It contains an acidic sequestring agent corrosively reacting with metals. (citric acid)
