A really really simple concept - I get everything else about respiration but I somehow am confused with the definition. I tend to overthink about the simplest ideas .
Internet sources say that respiration is:
The transfer of chemical potential energy from glucose into ATP.
Textbooks say:
The release of chemical potential energy from the breakdown of glucose to produce ATP.

Are they basically saying the same thing? I'm assuming both mean that.....
Glucose is broken down to release chemical potential energy; some of this energy is used to produce ATP, the rest of the energy left is then transferred to the newly synthesised ATP molecules?
HELP!!!

Yep, technically the same thing. Second one is slightly more explanatory through!

Would it be correct if I explain that respiration is where glucose is broken down to release chemical potential energy; some of this energy is used to produce ATP, the rest of the energy left is then transferred to the newly synthesised ATP molecules?

Or am I just confusing myself even more? :confused:

Yeah that's technically right. There are individual steps within respiration, the last one being oxidative phosphorylation. At this stage, ATP is produced, which aids the movement of H+ ions against its concentration gradient. When the H+ move back down, they release more ATP.

hope I didn't confuse you
