B. protists is the correct answer. I just took the test
3. Denature and decrease its activity
Changes in pH can affect the activity of enzymes. Enzymes have an optimal pH which they function most efficiently, and changes from this pH can cause denaturation of the enzyme. An important aspect of molecular biology is that structure means function. Denaturation affects structure of the enzyme and therefore, function. A pH that is too acidic or basic can disrupt the ionic and hydrogen bonds that maintain the 3D structure. This denaturation results in a loss of enzyme activity rather than increase.
Answer:
In the α helix structure, there is a hydrogen bonding between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain
Explanation:
The common secondary structure of protein are: α helix and β pleated sheet
α helix is a rod like structure.It is a right handed coil of amino acid residue on a polypeptide chain, which may be 4 units or 40 units long. The coil is held together by hydrogen bond between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain. This means that every complete turn of the helix is only 3.6 residues.
In an alpha helix, hydrogen bonds are formed between the carbonyl oxygen of one amino acid and the hydrogen attached to the nitrogen atom of another amino acid that is four residues away in the same polypeptide chain. This results in the characteristic spiral structure of an alpha helix.
In an alpha helix, a type of secondary structure in proteins, there is a specific pattern of hydrogen bonding that helps maintain its spiral shape. The hydrogen bond is formed between the carbonyl oxygen (C=O) of one amino acid and the hydrogen (H) attached to the nitrogen atom (N-H) of another amino acid that is four residues away in the same polypeptide chain. This repeated pattern of hydrogen bonding results in the characteristic spiral structure of the alpha helix. In terms of polypeptide numbering, if the amino acid at position n in the chain forms a hydrogen bond, then it does so with the amino acid at position n+4. This bonding pattern, along with the characteristics of the specific amino acids involved, contributes to the overall stability and function of the protein.

Answer:
burning of fossil fuels produces myriad types of greenhouse gases. usually, green house gas is important to keep the earth's temperature normal without being too cold. unfortunately, increase of fossil fuels burning in recent years have lead to excessive amount of the greenhouse gas in the atmosphere, which causes too much heat from the sun to be trapped in the earth atmosphere.
your answer would be sunlight
