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

Solutions

Expert Solution

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.

Sickle-cell anemia is an interesting genetic disease. Normal homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become very ill from the parasite and many die. Individuals homozygous for the sickle-cell trait (ss) have red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the genetic defect. However, individuals with the heterozygous condition (Ss) have some sickling...

Sickle-cell anemia is an autosomal recessive disease, people with the disease have a ss genotype and people without the disease have a SS genotype. People who have the disease get very ill, but people who have only one copy of the recessive gene are actually protected from getting malaria (Ss heterozygote genotype). Which area of the world is the frequency of sickle cell anemia the highest? Why do you think this is true (related to heterozygote advantage)? We talked about...

The cell membranes of mammalian red blood cells are permeable to urea. If red blood cells are dropped into a solution of urea that is identical in osmotic pressure (isosmotic) to the cytoplasm of the cells, although the cells do not swell and burst as quickly as when they are dropped simply into pure water, they eventually swell and burst. Explain. Also discuss how you would design a solution into which red cells could be placed without ever swelling. (Hint:...
