be classified as a ____________

Correct Answer: Lithotroph


Question 7.
Describe the energy transfer process relative to both ADP and ATP

Correct Answer: ATP has the energy (phosphate group) to donate, and ADP
can accept energy in the form of a phosphate group. Thus, ATP can be
dephosphorylated (ATP-----> ADP + Pi), while ADP can be dephosphorylated
into ATP (ADP + Pi -----> ATP)
• This phosphorylation process occurs in the mitochondria of chemotropic
