Flashcards in Enzymes - functions Deck (17):
1

Catalyses the synthesis of ATP and it is embedded in the thylakoid membrane.

ATP Synthase

2

Catalyses the hydrolysis of ATP

ATP Hydrolase

3

A co-enzyme that transfers hydrogen from one molecule to another during photosynthesis (reduces + oxidises)

NADP

4

Rubulose biphosphate (RuBP) combines with CO2 to form 2 x Glycerate 3-phosphate (3C) using the enzyme

Rubisco (ribulose bisphosphate carboxylic)

5

The three co-enzymes used in Respiration

NAD, FAD and co-enzyme A

6

An enzyme that synthesises RNA from DNA

RNA polymerase

7

An enzyme that makes a DNA copy of RNA

Reverse transcriptase

8

An enzyme that recognises specific recognition sequences and cuts DNA at these places

Restriction endonuclease enzyme

9

An enzyme that catalyses the hydrolysis of proteins

Peptidases

10

An enzyme that joins together the sticky ends of DNA fragments

Ligase

11

What is an enzyme?

A protein that speeds up the rate of chemical reactions, biological catalyst that doesn't get used up

12

An endopeptidase enzyme that hydrolyses peptide bonds within a protein

Dipeptidases

13

An enzyme that hydrolyses peptide bonds within a protein

Endopeptidase

14

An enzyme that hydrolyses the peptide bonds at the end of proteins to remove single amino acids

Exopeptidase

15

An enzyme that transfers hydrogen and electrons from one molecule to another

Dehydrogenase

16

An enzyme that converts ATP to cyclic AMP (aka. cAMP) in the response of Adrenaline

Adenylate Cyclase

17

An enzyme that activates a chain of reactions that break down glycogen >>> glucose

Protein Kinase A
