Answer:
Secondary level of protein structure
Explanation:
The proteins are formed of the monomer units called amino acids which bond with each other via peptide bond and form a linear peptide structure called the primary level structure of the protein.
The proteins to perform several functions in a cell undergoes structural conformation and attain the helical form called alpha helix due to the involvement of alpha carbon in bond formation and a pleated sheet called beta-pleated sheet due to the involvement of beta carbon. These structures are known as a secondary level of protein structure.
Thus, a Secondary level of protein structure is the correct answer.
Answer:
Blood Cells
Explanation:
The isotonic solution allow the cells to move water and nutrients in and out of the cells. This is necessary for blood cells to perform their function of delivering oxygen and other nutrients to other parts of the body.
