Chloroplast

Question 1

What are the functions of chloroplasts?

Answer 1

Chloroplasts use TOC and TIC. After the chloroplast sequence

Question 2

How many ways are there to insert into the thylakoid, and what are they?

Answer 2

There are four ways:

1) Sec pathway
2) SRP-like pathways
(both 1 and 2 utilizing ATP electrogradient)
3) TAT pathway (utilizing a Hydrogen Gradient)
4) Spontaneous entry.

Question 3

Describe the SRP-like pathway for thylakoid insertion.

Answer 3

Within the stroma, it uses Chloroplast SRP to bind to Chloroplast SRP receptor and inserts into the thylakoid lumen.

Question 4

What is the pH pathway for thylakoid insertion?

Answer 4

Within the stroma, it uses bound metal ions and enters the thylakoid lumen.
