Question

A man goes swimming in a pond. As he swims, which reaction provides energy to power his muscles?
A.)ATP regenerates from ADP using energy in glucose.
B.) The ADP molecule adds a phosphate group and produces ATP.
C.) ATP looses one phosphate group and converts to ADP.

Answer 1

Which statement is true about exergonic reactions?

Answer 2

Hey @shyannelucero and welcome to \(\LARGE \sf \bbox[#40B9E9]{\color{white}{Open}}\bbox[#A8CE91]{\color{white}{Study}}\)

I can reveal that ATP release energy when hydrolyzed to ADP or AMP and inorganic phosphate \(\sf P_{i}\) or pyrophosphate \(\sf PP_{i}\).
The reactions with their standard Gibbs energy of reaction could look like this:
\(\sf \large ATP + H_{2}O \to ADP + P_{i}+H^{+} ~ ~ ~ ~ ~ \ \Delta_{r} \it G^{\sf \Theta} \sf = -31 \frac{kJ}{mol}\)
\(\sf \large ATP + H_{2}O \to AMP + PP_{i}+H^{+} ~ ~ ~ ~ ~ \ \Delta_{r} \it G^{\sf \Theta} \sf = -45 \frac{kJ}{mol}\)
The negative value indicate the spontaneous tendency to convert the reactants into products and may drive other reactions.

For you other question we need the statements in order to help you.
