Photosynthesis 6.1

Question 1

What do Plant Cells have; that Animal Cells don’t?

Answer 1

Cell Walls and Chloroplast.
Animal Cells only contain membrane

Question 2

What does LEO mean

Answer 2

Loss of
Electrons =
Oxidized

Question 3

What does GER mean

Answer 3

Gain of
Electrons =
Reduced

Question 4

Is an Atom or Molecule that loses an electron oxidized?

Answer 4

YES

Question 5

what is the agent that donates an electron to another molecule?

Answer 5

Reducing Agent

Question 6

Compounds contain more Energy in Oxidized or Reduced form?

Answer 6

Reduced

Question 7

Can Oxidation and Reductions occur independently?

Answer 7

No. There has to be another molecule to pass energy onto.

Question 8

Where does the light dependent reaction take place?

Answer 8

In the Thylakoid of the Chloroplast.

Question 9

What carries the production of ATP across the Thylakoid Membrane?

Answer 9

Build up of H+ (Hydrogen Ions aka. Protons).

Question 10

How do so many protons get inside the Thylakoid?

Answer 10

As energy moves through etc (energy transport chain) they draw it into the Lumen.

Question 11

Where does the energy used to pull H+ into the Thylakoid Lumen come from??

Answer 11

Light. Photons of light!

Question 12

Why is the production of NADPH sooo important?

Answer 12

They are used to make sugar (Calvin Cycle)

Question 13

What is the Photosynthesis Equation?

Answer 13

CO2 (g) + H2O (l) + e- > C6H12O6 + O2
