Photosynthesis

Question 1

Noncyclic Photophosphorylation

Answer 1

Takes the energy in light and the electrons in h2o to make the energy rich molecules ATP and NADPH (note the P!). These reactions are often called light dependent reactions

Question 2

The Calvin cycle

Answer 2

Takes co2 from the atmosphere and the energy from ATP and NADPH to create a glucose molecule. Called “light independent” but only occurs in the presence of light bc it needs NADPH and ATP

Question 3

Parts of a chloroplast

Answer 3

Outer membrane: double phospholipid bilayer
Inter membrane space
Inner membrane: double phospholipid bilayer
Stroma: area inside inner membrane. Calvin cycle occurs here.
Thylakoids: pancake like membranes. A stack is called a granum.
Thylakoids lumen: the inside of the thylakoid.

Question 4

Chemiosmosis in chloroplasts

Answer 4

H+ ions accumulate inside thylakoids, creating a pH and electrical gradient. ATO synthase generates ATP (turbines on a dam)
The Calvin cycle produces G3P

Question 5

What are organisms that use sunlight as their source of energy called?

Answer 5

Photoautotrophs

Question 6

What are organisms that use chemistry as their primary source of energy called?

Answer 6

Chemoautotrophs

Question 7

Photophosphorylation

Answer 7

The process of using energy derived from light to generate ATP from ADP
