people with sickle cell anemia have deformed red blood cells that cant properly transport oxygen to cells. compared to a healthy human, sickle cell patients would be mostly defective in?
a) osmosis
b)ATP production
c) glycolysis
d) fermentation
Option (b) ATP production is correct answer.
Sickle cell anemia :-
• In this disorder, oxygen carrying capacity of RBC is
decreased.
• In this situation, less oxygen is delivered to cells of
body.
• In less oxygen, the processes which requires oxygen are
affected.
ATP production :-
• Maximum amount of ATP is produced by aerobic respiration with
help of oxygen.
• Oxygen acts as final electron acceptor in electron transport
chain in mitochondria. This electron transport chain is highly ATP
producing step of aerobic respiration.
• In absence of oxygen, this process will slow down or
defected.
Other options -
• Osmosis - this is passive movement of water across the membrane.
This process requires neither oxygen nor energy (ATP).
• Glycolysis - This is common step in both aerobic and anaerobic
respiration. This occurs in cytoplasm of cell and doesn't require
oxygen.
• Fermentation - This is also a oxygen independent step of cellular
respiration. It mainly takes place in muscle cells in absence of
oxygen.
