Partially blocks the H+/pyruvate symporter, interfering with the transport of pyruvate into the mito

Weight gain results from insufficient mitochondrial ATP production, so more has to be made from glycolysis.

Substance’s Effect: Partially blocks the H+/pyruvate symporter, interfering with the transport of pyruvate into the mitochondria.

1. Causes weight loss or weight gain?

Substance’s Effect: Increases the number of free hydrogen ions or protons (H+) in the intermembrane space of the mitochondria (between the outer and inner membranes). 
2. Causes weight loss or weight gain?

Substance’s Effect: Makes the lipid bilayer of the inner mitochondrial membrane highly permeable to (H+) protons.
3. Causes weight loss or weight gain?

Substance’s Effect:Impedes the binding of NAD+ to electrons.
4. Causes weight loss or weight gain?




I got the first two questions I just wasn't sure if I was right or not, and the last two questions I just flat-out could not understand. We didn't really discuss this in class and I couldn't find it in my notes or on google.

Thank you so much for helping me! I think this forum will really help me understand Biology a lot more.
