energy production

Postby alanaarchbold » Sat Jan 26, 2019 4:53 pm

Lavelle briefly talked about how one heartbeat takes 1 joule of energy. Does that energy come from the bonds breaking in glucose?

Cellular respiration breaks down the energy contained by glucose and stores the energy in the form of ATP. The heart uses ATP but not the energy from breaking glucose bond directly.

The heart uses ATP which is created in the body through the breakdown of glucose. There's a cool video https://www.youtube.com/watch?v=v_qYy7LiTdc that explains the process and how cardiac metabolism works :)

Glucose is used to form ATP, which is the actual stored energy that the heart uses. So breaking glucose bonds is not the direct source of energy.

The breaking of bonds between glucose creates an exothermic reaction which subsequently powers the process of cellular respiration an endothermic process. Cellular respiration produces ATP which dissociates into ADP and P(inorganic) and produces a muscle contraction within the heart.
