If shape of a protein is changed its function is altered. This might change or stop a particular biochemical pathway in which that enzyme was critical. Specific 3D shape of each protein is very essential for its function. Change in shape of proteins is caused by a mutation in the DNA.

How can changing even one amino acid affect the protein?
changing even one amino acid would change the whole whole sequence hence, change the structure(shape) of the protien because the amino acid ie; the (primary structure) determines the 3 dimensional shape of the protien in the first place,this because the polypeptide posses the positive charge and the negative either side of the peptide bonds these charges form the bonds in the primary-teritary making it into a 3d shape, in conclusion changing one amino acid would disrupt the charges and the way the polypetides are bonded intially changing the protiens structure.

How might a point mutation in a gene impact the structure and function of the resulting protein?
A point mutation in a gene can change a single nucleotide in the DNA sequence, leading to a different amino acid being incorporated into the protein during translation. This can alter the structure of the protein, affecting its shape and potentially disrupting its function. The change in amino acid sequence may also impact the protein's ability to interact with other molecules or perform its intended role in the cell.
What protein changes shape when ca2 plus binds to it?
Calmodulin is a protein that changes shape when it binds to calcium ions. This change in shape allows calmodulin to interact with and activate various target proteins involved in signaling pathways within cells.
Changing one amino acid with a protein could change what about the protein?
It will depend on how different the amino acid is to the one it replaced. If the structure and/or charge is quite different, a change of one amino acid can change the entire 3D structure of the protein. This will affect the proteins function.
When a signal molecule binds to a receptor protein the receptor protein may change the?
shape, leading to activation of signaling cascades within the cell. This activation can lead to changes in cell behavior or gene expression.
How does changing a nucleotide in the DNA code for b-globin change the characteristics of hemoglobin?
Due to change in nucleotide, a completely different protein is coded for. The normal protein has glutamic acid, is hydrophillic; however, the mutated protein incorporates valine, a hydrophobic amino acid instead. This causes the overall haemoglobin protein to distort into a sickle shape, rather than a concave shape. As a result, sickle cells have a much shorter lifespan than their normal counterparts.
Why does changing shape of an object dose not change the density?
Density is a property that depends on the mass and volume of the object, not its shape. Changing the shape of an object does not alter the amount of mass or volume it contains, so the density remains the same.
Does the shape of an object change its density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.
How does the change in the 17th nucleotide affect the shape of red blood cell of a person with sickle cell disease?
In sickle cell disease, a mutation occurs at the 17th nucleotide of the hemoglobin gene, where adenine (A) is replaced by thymine (T). This single nucleotide change results in the substitution of glutamic acid with valine in the hemoglobin protein. Consequently, under low oxygen conditions, the altered hemoglobin (HbS) tends to polymerize, causing red blood cells to assume a rigid, sickle shape instead of their normal disc shape. This abnormal shape leads to blockages in blood flow and reduced oxygen delivery throughout the body.
How can one amino acid have a great effect?
If you mean how does changing one amino acid have a great effect, that single change may alter the shape of the protein in a critical area, which can make the protein function poorly or not at all.
Is a cloud changing shape a chemical change?
No. it is not. It is a physical change.

Why is it important that a protein keep in shape?
because the shape of a protein allows it to perform its particular job
What is changing shape but not changing volume?
A cloud would be an example of something changing shape but not changing volume. As a cloud moves and disperses, its shape can change while the total volume of its water droplets remains the same.
How might a point mutation in a gene impact the structure and function of the resulting protein?
A point mutation in a gene can change a single nucleotide in the DNA sequence, leading to a different amino acid being incorporated into the protein during translation. This can alter the structure of the protein, affecting its shape and potentially disrupting its function. The change in amino acid sequence may also impact the protein's ability to interact with other molecules or perform its intended role in the cell.
Why will the big dipper change in shape?
the universe is always changing
Which one is not a sign of a chemical change change in shape bubbling smoking changing color?
Changing shape is not typically a sign of a chemical change. Chemical changes involve the rearrangement of atoms and molecules to form new substances with different properties. Shape change is more likely a physical change.
