Responda
- True
- False
Questão 9
Questão

- False
Questão 10
Questão
What is a photosystem?
Responda
-
A group of hundreds of chlorophyll molecules located on the inner membrane of the chloroplast
-
A group of hundreds of chlorophyll molecules located in the stroma of the chloroplast
-
A group of hundreds of chlorophyll molecules located in thylakoid membranes
-
A group of hundreds of chlorophyll molecules located in the cytoplasm of the plant cell
Questão 11
Questão
How does chlorophyll become photoactivated?
Responda
-
The light energy absorbed by the chlorophyll raises an electron in the molecule to be raised to a higher energy level
-
The light energy absorbed by the chlorophyll moves an electron in the molecule to a lower energy level
Questão 12
Questão

Responda
-
To the stroma
-
To a series of electron carriers in the thylakoid membranes
-
To a series of electron carriers in the mitochondrial membrane
Questão 13
Questão
Each time the electron passes to a new electron carrier, it gives up some of its energy. This keeps happening until, at some stage, enough is made to form a molecule of ATP. This process is called what?
Responda
-
Osmosis
-
Facilitated Diffusion
-
Active transport
-
Chemiosmosis

Responda
-
cyclic photophosphorylation
-
non-cyclic photophosphorylation
