Question

It takes 1 molecule of glucose to make 30 molecules of ATP. How many molecules of glucose are needed to make 6000 molecules of ATP in aerobic respiration?

Answer 1

`"200 glucose"`

Explanation:

I think the molecules of `"ATP"` produced is closer to `36`, but anyway...

`color(white)(---)`

If `"1 glucose"` gives us `"30 ATP"` molecules, then we can set up the relationships as follows:

`color(white)(---)color(purple)[("1 glucose")/("30 molecules of ATP") or ("30 molecules of ATP")/("1 glucose")`

`color(white)(---)`

Knowing this, we can figure out the number of glucose molecules needed as follows:

`(6000 cancel"molecules of ATP")/(1)*color(purple)[("1 glucose")/(30 cancel"molecules of ATP")] = barul"| 200 glucose |"`
