Is Light-dependent reactions stroma?

um here is something idk if u understand

Explanation:

In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.

but there is no

i guess you forgot putting it.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
