Is it true that the breakdown of food molecules in the gut does not require coupling of atp hydrolysis, but enzymes are required to speed up the spontaneous reaction?

glycolysis is a process that fuel your metabolism. it is apart of cellular respiration the process that produce atp.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
