Chemiosmosis/Photosynthesis Questions!

I am very confused by these photosynthesis concepts. Are the different types of electron flow, linear and cyclic, a part of chemiosmosis? Or are they all separate parts of photosynthesis? Is ATP synthesized using all three? Please help, I don't understand any of this :(

Answer 1

Can you help me understand this? @pooja195

Answer 2

ok first do you know what photosyntheisis is?

Answer 3

Process by which plants use sunlight to synthesize foods

Answer 4

good what is chemiosis

Answer 5

I guess I don't know a lot about it. I know that chemiosmosis in mitochondria and chloroplasts generates ATP.

Answer 6

Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient. More specifically, it relates to the generation of ATP by the movement of hydrogen ions across a membrane during cellular respiration or photosynthesis.-google now what do you think

Answer 7

Hmm. Well, then I guess the electron flows must be a part of that?

Answer 8

yeo :)

Answer 9

*yep and whats your next question

Answer 10

Well, I'm working on essay questions. The one asks to explain how ATP is synthesized through photosynthesis. So would I talk about chemiosmosis, then describe the electron flows that take place within it?

Answer 11

yep

Answer 12

Okay. The next one wants to know about the energy transfers during chemiosmosis and the role of ATP in the process. It seems like a weird question to me. Isn't the role of ATP to just be generated? It doesn't really do anything else in the process, does it?

Answer 13

Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent.-google-this is what it does

Answer 14

But that isn't really the role of ATP in chemiosmosis, is it? I thought that sort of thing took place after.

Answer 16

So the role is that it is generated in chemiosmosis? That's all the page really seems to say.

Answer 17

yes that the role of it just wanted you to read and understand

Answer 18

Okay, thanks :) Sorry for so many questions! Do you think you could read what I have so far for these essay questions and tell me if I'm missing anything? As long as you think you have enough understand of the subject to be able to spot any errors :P

Answer 19

understanding*

Answer 20

YEP! and never apologize for asking questions :D

Answer 21

ok its fine try explaing things in detail more

Answer 22

which process and to me it seems fine :)

Answer 23

Chemiosmosis, I guess. Even though linear electron flow is part of it, it seems like they're very different. Or maybe it's just the way my book explains them that makes the processes seem like two completely different things.

Answer 24

yea it might be your book continue with your esaay pm me with questions

Answer 25

Okay, thank you so much for all your help!

Answer 26

It looks like a Test question....
