ATP

Question 1

ATP

Answer 1

adenosine triphosphate is a phosphorylated nucleotide formed from a nitrogen containing organic base adenine, a 5 carbon ribose sugar and a chain of three phosphate groups

Question 2

why is ATP a good energy source but poor long term energy store

Answer 2

phosphate bonds are relatively unstable

Question 3

ATP is the …

Answer 3

immediate energy source as the cell cannot get energy directly from glucose

Question 4

draw a diagram of ATP

Answer 4

-

Question 5

synthesis of ATP condensation reaction and what each symbol represents

Answer 5

ADP + Pi <——> ATP +H20
ADP = adenosine di phosphate
Pi = inorganic phosphate ion
ATP = adenosine tri phosphate
above arrow ATP synthase energy used

Question 6

uses of ATP

Answer 6

energy requiring processes cells
- phosphorylation of compounds to make them more reactive such as glucose to glucose phosphate in glycosis (adding of a phosphate group)
- active transport ATP provided the energy to change shape of carrier proteins in plasma membranes moving molecules against a gradient
- metabolic processes such as synthesizing glycogen from glucose, polypeptides from amino acids
- exocytosis secretion or release of products from the cell
- movement muscle contraction and movement of cilia
