Question A2: Make predictions: In the table below, describe what would happen if the protein complex listed were inhibited. If this piece of the If this piece of the pathway is inhibited, pathway is inhibited, what molecules will what molecules will be abnormally accumulate abnormally depleted in (build up) in the the organelle? organelle? H2O 02 Consider this piece of the pathway Any complex in the chloroplast's electron transport chain A complex in the mitochondrial electron transport chain ATP Synthase (in either chloroplasts or mitochondria) NADH, FADH NAD+, FAD ATP H+(protons)

Ignore words in blue.

Answer 1

if,any complex in the chloroplast electrons transport chain if inhibited then electron will not transported along its pathway from photosystem I and ii and then to FNR which converts NADH TO NADH2.

IF ELECTRONS IS NIT TRANSPORT , THEN NADH WILL BE ACCUMULATED AND NADH2 WILL BE DEPLETED BECAUSE ALREADY PRESENT NADH2 WILL BE USED TO MAKE GLUCOSE.(FOOD).

AS IN THIS PROCESS PROTON GRADIENT IS SET UP WHICH IS USED TO PRODUCE ATP .SO THIS ALSO CAN AFFECT ATP PRODUCTION SND THUS ADP WILL ACCUMULATED AND ATP WILL BE DEPLETED AS IT WILL BE USED UP. But this two can be produced by other means like TCA CYCLE can produce NADH2, ATP CAN ALSO BE PRODUCED BY GLYCOLYSIS OR TCA CYCLE.

BUT H20 WILL BE ACCUMULATED BECAUSE ELECTRON WILL NOT BE TAKEN UP BY CHLOROPHYLL MOLECULES AND THUS WATER WILL NOT BE SPLIT INTO OXYGEN ,SO OXYGEN WILL BE DEPLETED AND H20 WILL BE ACCUMULATED.

DEFECT IN COMPLEX OF MITOCHONDRIAL ELECTRONS TRANSPORT CHAIN-

NADH2 AND FADH2 WILL BE ACCUMULATED BECAUSE THIS SUPPLIES ELECTRONS TO THE OXYGEN AND ATP IS PRODUCED AND WATER IS PRODUCED AND NADH2 IS OXIDIZED TO NAD+ AND FAD+.

AND ALSO, IN THIS PROCESS, H+ GRADIENT IS SET UP BETWEEN MITOCHONDRIAL MATRIC AND INTER MEMBRANE SPACE OF MITOCHONDRIA , ATP SYNTHASE USES THIS VOLTAGE AND ELECTRON GRADIENT TO PRODUCE ATP FROM ADP , AND THUS ATP WILL BE DEPLETED AS IT WILL NOT BE PRODUCED AND WILL BE USED UP BY OTHER CELLULAR PROCESSES.

ADP WILL BE ACCUMULATED.

IF ATP SYNTHASE IS NONFUNCTIONAL ,THEN, ADP WILL BE ACCUMULATED AND ATP WILL BE DEPLETED ONLY I HAVE DESCRIBED IN UPPER SECTION.

thank you a lot.
