ATP

Question 1

ATP

Answer 1

Adenosine triphosphate

Single atp molecule is a nucleotide derivative and is formed from a molecule of ribose, adenine and 3 phosphate groups

Acts as an intermediate or immediate energy source - the molecule is adapted for this function

Question 2

Ribose

Answer 2

Pentose sugar

Question 3

Adenine

Answer 3

Nitrogenous base

Question 4

How is atp different to dna nucleotide

Answer 4

DNA - deoxyribose, 1 phosphate, atcg

ATP - ribose, 3 phosphate, Adenine

Question 5

How is atp different to rna nucleotide

Answer 5

RNA - 1 phosphate, AUCG

ATP - 3 phosphates, A

Question 6

Nucleotide derivative

Answer 6

Has a similar structure to a nucleotide

Question 7

Pi

Answer 7

Inorganic phosphate

Question 8

Hydrolysis of ATP

Answer 8

ATP > ADP + Pi

Question 9

Examples of energy requiring reactions

Answer 9

Active transport, co-transport, mitosis/meiosis

Question 10

Phosphorylate example

Answer 10

Glycolysis

Question 11

Condensation of ATP

Answer 11

ADP + Pi > ATP

Question 12

Balanced equation for aerobic respiration

Answer 12

C6H12O6 + 6O2 > 6CO2 + 6H2O + ATP

Net producer of atp

Question 13

Anaerobic respiration

Answer 13

C6H12O6 > 2C3H6O3 + 2ATP

Glucose > ethanol + carbon dioxide + energy

Both produce 2 ATP

Question 14

Photosynthesis

Answer 14

6CO2 + 6H2O > C6H12O6 + 6O2

First part, LDR makes 2 ATP, 2nd part LIR uses 2 ATP

So not net consumer or producer of ATP

Question 15

Parts of cell associated ATP production associated with

Answer 15

Mitochondria

Chloroplasts

Cytoplasm

Question 16

Advantages of atp

Answer 16

Made and synthesised in single reaction

Cycle so it can be resynthesizesd if needed

Releases a small, manageable amount of energy

Relatively small molecule, so it can diffuse within cells

Phosphorylates, making phosphorylated substances more reactive/ lowers activation energy

Question 17

Disadvantage of atp

Answer 17

Cannot be stored so it has to be synthesised near to where it is used
