Solution-How does the acetyl-coa move from the matrix to | Homework Help
In mammalian cells, fatty acid synthesis occurs in the cytosol. The beginning substrate for this series of reactions is acetyl-CoA, which is formed in the mitochonrdrial matrix. How does the acetyl-CoA move from the matrix to the cytosol?
a.Acetyl-CoA reacts with oxaloacetate and leaves the matrix as citrate via the citrate transporter.
b.Acetyl-CoA combines with bicarbonate and is transported out of the matrix as pyruvate.
c.There is a specific transport protein for acetyl-CoA.
d.Acetyl-CoA is a non-polar molecule that can diffuse across all membranes.
e.Inner and outer mitochondrial membranes are freely permeable to acetyl-CoA due to the presence of transmembrane pores.
