Exam preparation - The structure and function of ATP

9 important questions on Exam preparation - The structure and function of ATP

I) What are the components that make up a single ATP unit?

One adenine (N-containing base), one R sugar, three P

I) How are the components that make up a single ATP unit connected?

The A (N-containing base) bonds to a R sugar via a G bond

The R bonds to a P via a phosphoester bond

There are three P

Each pair of P connects by HE phosphoanhydride bonds.

Ii) Do catabolic reactions create or use ATP?

Create
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

ii) In a catabolic reaction such as glycolysis, is ATP used or produced?

Some CTB reactions produce ATP directly (G)

Other CTB reactions are preparation steps for other metabolic processes that produce ATP (ETC)

Iii) Do anabolic reactions create or use ATP?

Use

Iii) In an anabolic reaction such as the assembly of a protein chain from individual amino acids, is ATP used or produced?

Connecting multiple compounds together to make a larger compound will usually require ATP


iv) How much energy is released from ATP when one of its phosphoanhydride bonds (that connect the phosphates together) is broken and it becomes ADP?

When one phosphoanhydride bond is broken, one P (Pi) is released along with 7.3 Kcal/mole of energy


iv) What can the energy released from ATP be used for?

To power the C processes that keep the C functioning and alive

(v) What would happen after enough cells die from lack of ATP production?

Organs would begin to fail and the individual would die

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
