|
Acetyl-CoA is joined up to a ____ to form ____
|
|
6 carbon compound; acetate
|
|
|
3 carbon compound; acetyl-CoA
|
|
|
4 carbon compound; acetyl-CoA
|
|
|
4 carbon compound; citric acid
|
|
|
6 carbon compound; citric acid
|
Explanation:
Detailed explanation-1: -In the first step of the citric acid cycle, acetyl CoAstart text, C, o, A, end text joins with a four-carbon molecule, oxaloacetate, releasing the CoAstart text, C, o, A, end text group and forming a six-carbon molecule called citrate.
Detailed explanation-2: -The citric acid cycle begins by acetyl-CoA (2 carbons) combining with oxaloacetate (4 carbons) to form citrate (aka citric acid, 6 carbons).
Detailed explanation-3: -Each Acetyl CoA consists of 2 carbon atoms.
Detailed explanation-4: -To start the cycle, an enzyme fuses acetyl CoA and oxaloacetate together so that citric acid is formed (a 2-carbon molecule + a 4-carbon molecule = a 6-carbon molecule!).
