4. Where does the chemical energy to produce ATP come from? 1. the addition of a phosphate group to ATP

2. from SRP

3. the conversion of ATP to ADP

4. from the Space

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!
