Week 2

Question 1

Describe the light-dependent photosynthesis

Answer 1

Thylakoid membrane of chloroplast

non-cyclic phosphorylation - (Photosystem II) photos sunlight excites the e and bust them to a higher energy level –> travels down ETC –> produce ATP

photosystem I- photos sunlight excites the e and bust them to a higher energy level –> form NADPH

cyclic phosphorylation- occurs in the stroma lamella and its main purpose is to continue producing ATP by using photosystem I

Question 1

Describe photosynthesis, chlorophyll

Answer 1

6CO2 + 6 H2O –> glucose + 6 O2
occurs in the chloroplast of bacteria, plants

chlorophyll captures sunlight to convert into glucose and water
- a type of porphyrin that contain Mg in the center

stroma- cytoplasm
- where the Calvin cycle takes place

Question 2

what is the main product of the light reaction of photosynthesis

Answer 2

ATP, NADPH & O2
