does glycolysis happen in the cytoplasm or cytosol.

The cytoplasm contains cytosol, the cytoplasm is basically the area where the intracellular liquid is and the cytosol is the liquid itself

so it isn't the process of cellular respiration?

also i wanted to say that does anaerobic and aerobic respiration go through the same process, like where does it stop been the same can you explain that to me please.

Basically in the absence of oxygen, it switches to anaerobic respiration after glycolysis
Alright so this image might help you make sense of it
Green is aerobic respiration and red is anaerobic

Let me know if you have any questions

Those are the three STAGES of cellular respiration.

The only part of anaerobic and aerobic respiration that is the same is glycolysis, which occurs in the cytosol.

It is basically interchangable at this level the only time you need to move away from this terminology is if you are only talking about anaerobic respiration om its own.

Glycolysis is the stage that is both in aerobic and anaerobic

Then the krebs cycle and the ETC is only for aerobic

This is my teachers diagram, he drew the nucleus to show it was a cell he was drawing - it's not really relevant

Yeah, it would be possible since your final sac score is mostly dependent on your sac ranking rather than actual sac score. Plus there should be plenty of sacs to come this year to improve your rank if it is low.

Hi!
I would like to ask about photosynthesis. If the input of H20 in the light-dependent stage is 12, thus 24 hydrogens, why is there only 12NADPH coenzyme as an output. Isn't there supposed to be 24NADPH in the output as NADPH is a carrier of hydrogen?  Or is some carried in the 12ATP that is also a output of the light independent stage?

Thanks in advance! =)

Is rRNA a structural protein or is the ribosome the structural protein
I'm trying to read my notes from last year and I've written:
rRNA
- Found in ribosomes are 60% rRNA and 40% protein
- structural proteins

I am unsure about what you mean, but rRNA combines with many different proteins to form a ribosome. In a ribosome, 60% rRNA and 40% protein is found, like you said. rRNA is a type of non-coding RNA, and is made of nucleic acid monomers, so it isn't a type of protein. A ribosome isn't a protein either, since it is made of both proteins and rRNA.

Haha, I'm not sure where I got this "structural protein" info from and will probably just take it out of my notes - who knows what I meant! 😂😂😂

rRNA is a nucleic acid. Your structural protein comment probably comes from a combo of the fact that rRNA forms the structure of the ribosome alongside proteins. I suspect your brain just unkindly decided to put those two things together for you when that's not really the case!!
