Question 1

what is the reaction called when ATP is being broken down? and what is the opposite called

Answer 1

broken down - Hydrolysis

formed back into atp - condensation

Question 2

what are some similarities between atp and dna nucleotide

Answer 2

*both contain at least one phosphate
*both contain a pentose sugar
*both contain a base

Question 3

differences between atp and nucleotides

Answer 3

*DNA nucleotide contains deoxyribose sugar whereas atp contains ribose sugar
*dna nucleotides can form polymers whereas atp cant
*atp has 3 inorganic phosphate groups whereas nucleotide only has one
*atp will always have adenine as its base whereas dna nucleotide will be able to change its base

Question 4

how much energy is released each time ATP is broken down?

Answer 4

30.6kjmol -1

Question 5

extra info abt mitochondria

Answer 5

*the inner and outer membrane together are called the envelope
*matrix is gel-like and contains lipids, dna, ribosomes and enzymes
*generally sized between 2-5 microns in length
*liver cells contain many
*important: inner membrane is impermeable to small ions including protons/H+ ions *

Question 6

*krebs cycle
*oxidative phosphorylation

Question 7

glycolysis

Answer 7

*generates ATP and pyruvate
*occurs in cytoplasm
*is a stage of aerobic and anaerobic respiration

Question 8

link reaction

Answer 8

generates Acetyl Co A
