What forms NADPH

A

NADP+ with two high energy electrons and a single proton

29
Q

What is photosynthesis

A

Process which light from sun is combined with carbon dioxide gas and water to form glucose and oxygen

30
Q

What does photosynthesis depend on

A

Chlorophyll

31
Q

Where is chlorophyll located and take place

A

Chloroplasts

32
Q

Where does carbon dioxide come from

A

Diffuses into plants from air through stomata (on the under leaf)
Produced within plant by respiration

33
Q

Crop growth in greenhouses

A

Artificial light

Adding co2 eg burning gas

34
Q

Where does the light and dark stage take place

A

Chloroplast
