Explanation

Question 3 of 12

1

Select the equation which BEST outlines the exergonic process of ATP hydrolysis.

Select one of the following:

  • ATP → ADP + Phosphate group + Energy

  • ATP → ADP + PO3 + ATP

  • ADP + Phosphate group + Energy → ATP

  • ADP → ATP

Explanation

Question 4 of 12

1

Select one of the following:

  • True
  • False

Explanation

Question 5 of 12

1

ATP phosphorylates molecules which would not normally react and allows endergonic processes to occur.

Select one of the following:

  • True
  • False

Explanation

Explanation

Question 8 of 12

1

Which statement about the ATP cycle is CORRECT?

Select one or more of the following:

  • ATP hydrolysis forms ADP and a phosphate group, as well as producing free energy for endergonic processes

  • ATP will readily reform from ADP and a phosphate group while free floating in the cytoplasm.
