Glutamic acid (Glu) and valine (Val) are two amino acids with different molecular structures. (Glutamic acid is a strongly hydrophilic molecule, and valine is a strongly hydrophobic molecule). Why do you think switching the hemoglobin gene's sixth amino acid from glutamic acid to valine would affect the hemoglobin protein

Hemoglobin is the red color pigment that gives the red color to the blood. This pigment is responsible for the binding and transport of oxygen to the different parts of body.

The change in the amino acid from glutamic acid to the valine affects the protein structure and increases the hydrophobicity of the protein. This affects the protein folding and changes the function of the protein as protein are specific to their structures. The structure of the RBCs become sickle cell from the normal shape.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
