respiration

Question 1

process of glycolysis

Answer 1

phosphorylation of glucose
2atp+glucose=gp-splits into 2 tp
then 4 atd phosphorylate into ATP and 2 NAD oxidise tp to form 2nadh forming 2xpyruvate
net 2 atp + 2nadh

Question 2

link reaction

Answer 2

pyruvate decarboxylated and oxidised form 2 nadh forming acetyl
coa binds to acetate forming acetyl coa

Question 3

Krebs cycle

Answer 3

de na de na de fa na
acetyl co a attatches to 4 carbon compund repeat cycle forming citrate

Question 4

oxidative phosphorylation

Answer 4

NADH+fadH releases hydrogen splitting into protons and electrons which are carried along etc-
move across inner mitrochnadrial membrane
release energy at terminals
hydrogen moves over by active transport
electrochemical gradient forms
facilitated difusion through atp synthase
oxygen picks up electrons to form h20 as its the final terminal

Question 5

anaerobic respiration in plants where does it occur

Answer 5

cytoplasm

Question 6

plants anaerobic repsiration process

Answer 6

pyruvate-ethanal (c02 given off)-ethanol(NAD reduces ehtanal-nadh)

Question 7

anaerobic respiration in animals

Answer 7

pyruvate+nadh=ethanol+nad allows for glycolysis to carry on

Question 8

where does the krebs + oxidative phosphorylation cycle occur

Answer 8

mitrochondrial matrix

Question 9

what is the etc

Answer 9

series of embedded proteins with mitrochondira membrane

Question 10

what is an issue with lactate production

Answer 10

ethanol dissolves membranes so may kill them+acidic
