It would be carbon dioxide
Answer: Chemiosmotic coupling hypothesis
Explanation:
Chemiosmotic coupling hypothesis.
The coupling of oxidation with phosphorylation is termed oxidative phosphorylation.
The Chemiosmotic hypothesis state that electron transport chain and ATP synthesis are coupled by a proton gradient across a semi permeable membrane. The transport of protons from inside to outside of inner mitochondrial membrane is accompanied by the generation of a proton gradient across the membrane.
Protons (H+ ions) accumulate outside the membrane, creating an electrochemical potential difference. This proton motive force drives the synthesis of ATP by ATP synthase complex.
It is balanced by the outward force of pressure.
The answer is synarthrosis.
Suture is a type of joint that is only found in the skull. The skull bones are bound together by Sharpey's fibers. This joint only allows a tiny amount of movement under normal conditions, making it a synarthrosis joint.
