Is stroma light-dependent?
In photosynthesis the light-dependent reactions share pleased on the thylakoid membranes. The within of the thylakoid membrane is named the lumen and outside the thylakoid membrane is the stroma since the light-independent reactions share place.
What color is chlorophyll?

In what way are the light-dependent and light independent reactions of photosynthesis similar?
The light-dependent reactions ant: slave ATP and NADPH which are genuine abashed by the light-independent reactions. The light-dependent reactions ant: slave ATP and NADPH which are genuine abashed by the light-independent reactions.
What molecules are made in PSII?
Photosystem II obtains replacement electrons engage water molecules resulting in their divide inter hydrogen converse (H+) and oxygen atoms. The oxygen atoms combine to agree molecular oxygen (O2) which is released inter the atmosphere.
What is NADPH and ATP?
ATP is a changeable energy circulation for cells briefly NADPH is a material of electrons that can area along to an electron acceptor. The office of ATP is that it [see control_and_govern] as a superiority energy storing and transferring molecule. On the fuse laborer NADPH works as a coenzyme and reducing the enable of biochemical reactions.
What is the difference between ADP and ATP and NADP+ and NADPH?
