Hi, Could someone explain to me how exactly ATP changes the shape of a transport protein? If ATP, when hydrolyzed, releases free energy, how does this energy change the conformation of the structure of the protein? Additionally, why must a phosphate group attach itself to it? Thanks!

Thanks! But how does that relate to photon absorption?

Double bonds make the molecule shorter than single bonds? How does that help with photon absorption?

Homework Statement Why does the conjugated system (alternance of single and double bonds) of chlorophylles help with photon absorption? The Attempt at a Solution Since two carbon atoms are equal in electric negativity, no one atom hogs the electrons. In this way, it is easier for photons to...
