QUESTION3

Question 1

DRAW A LABELLED DIAGRAM OF ATP

Answer 1

LABEL

Question 2

DESCRIBE TWO STAGES IN THE PROPVCESS OF GLYCOLYSIS ,OUTLINE THE NET ENRGY YILED OF THE OVERALL PROCESS IN TEMRS OF ADP AND NADH

Answer 2

STAGTE1-PREPARATORY PHASE
PHOSPHORYLATION OF GLUCOSE REQUIRES ATP AS ENERGY THIS PROCESS YIELDS TWO 3 CARBON MOLECULES CALLED 2-GLYCERALDEHYDE-3-PHOSPHATE

STAHE 2 PAY OFF PHASE
0XIDATION OF GLYCERALDEHYDEBY REMOVAL OF 2H
LEADING TP FORMATION OF 2MOLECULES OF PYUVARTE WHILE SIMITANOEULSY GENERATING ATP
PROPDUCES NET YIELD-2ATP MOLECULES 2 NADH

Question 3

ELECTRON TRANSPORT CHAIN

Answer 3

-SEQUENEC OF PROTEINS OMN THE INNER MITOCHONDRIAL MEMBRANE -ELECTRONS MOVE FROM PROTEIN TO PROTEIN AND GIVE UP ENERGY TO GENERATE ATP-AS ELECTRONS ARE DROPPED ,PROTONS ARE MOVED ACROSS INTO THE INTERMEMBRANE SPACE TO FORM A PROTON GRADIENT

Question 4

ATP SYNTHASE

Answer 4

ANOTHER PROTEIN COMPLEC IN TH EMITOCHONDRIAL MEMBRANE HARNESSES THE ENERGY FROM THE PROTON GRADIENT TO GENERATE ATP
