ATP

Question 1

State the components of ATP

Answer 1

-nitrogenous base of adenine
- ribose sugar
- 3 phosphate groups

Question 2

What does ATP stand for

Answer 2

Adenosine triphosphate

Question 3

What type of reaction is the hydrolysis of ATP

Answer 3

An emergencies reaction as it releases 30.6kJ of energy per every mol

Question 4

State the equation of the hydrolysis of ATP

Answer 4

ATP + water = ADP + Pi + 30 .6kJ of energy
Reversible

Question 5

What is phosphorylation

Answer 5

The addition of phosphate to ADP

Question 6

ATP vs Glucose

Answer 6

Hydrolysis of ATP is a single reaction that releases energy immediately
Glucose involves many intermediates and takes longer for energy to be released

Only 1 enzyme needed to release energy from ATP
Glucose requires many to release energy

ATP releases energy where and when it is needed in small amounts
Glucose contains large amounts of energy and releases it all at once

ATP contains a comment source of energy for many different chemical reaction increasing efficiency and control by the cell

Question 7

Roles of ATP

Answer 7

N - nerve transmission sodium potassium pumps actively transport sodium and potassium ions across the axon membrane
A - active transport - to change the shape of the carrier proteins and allo molecules or ions to be moved against a concentration gradient
M - movement - for muscle contraction , cytokinesis
M - metabolic processes - to build large complex molecules from mallet simple molecules - dna synthesis from nucleotides , proteins from amino acids
S - secretion -packaging an transport of secretory products into vesicles in cells
