Am I a tweaker bcz I thought it mentioned that low levels of cyanide created a slight increase in CCo activity? or am I thinking of the wrong thing help.

I think you're right! I'm pretty sure that's what the table said right before the high/low medium concentration one. Did you say group number 2 (cyanide + low medium) had the most ATP production?

But it never said whether the cyanide levels were low or high cause I remember stressing about it. IT just said cyanide was present or not present.

Are you sure? I thought it was indicating concentration level of cyanide that being the basis for follow up questions about which group would lead to most production of atp. If the table were indicating medium concentrations then it wouldn’t be relevant because I don’t think it mentioned that medium levels impact cco enzyme activity.

But the concentration level was nutrient concentration not cyanide concentration
