What are the stages of respiration in lots of detail?

I don’t understand the stages of respiration, like glycolsis, krebs cycle, electrons transfer.

i also don’t understand ATP, like what exactly is it and how does it get charged, and does it get produced or is it a protien? does it ever die? and does it create energy, or carry energy, or releas enerfy and how does the ATP release energy?

also i don’t understand photosynthesis either, like all the detail.
thank you
