Each round of the citric acid cycle begins when the four-carbon molecule oxaloacetate is converted to the six-carbon molecule citrate. as the cycle progresses, two carbons are eliminated to regenerate the oxaloacetate. the added carbon is supplied by and the two eliminated carbons are released as
a. co₂; acetyl-coa
b. atp; acetyl-coa
c. acetyl-coa; co₂
d. co₂; nadh
e. co₂; pyruvate

C. Acetyl-CoA; CO₂

Explanation:

Acetyl-CoA undergoes into the citric acid cycle and combines with oxaloacetate to produce citrate which is a 6 carbon molecule. Citrate then undergoes 2 steps and yields alpha- ketoglutarate and removal of carbon dioxide takes place. Alpha- ketoglutarate then undergoes reaction and yields succinyl CoA which is 4 carbon molecule and produces 1 molecule of carbon dioxide.

Hence, the correct option is C

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
