What activities would be inhibited by a drug that specifically blocks the addition of phosphate groups to proteins?

receptor tyrosine kinase activity.

Explanation:

Theses are the receptors  present on the cell surfaces of cells  with affinity fpr specific polypeptides- gwoth factors, hormones and cytokines. They are regulators of normal cellular processes. E.g e development  and progression of cancer in most cells

Mutation in their protein  sequence   leads to  faulty protein expression.

RTK activity

Explanation:

RTKs are considered to be transmembrane protein receptors that help cells interact with their neighbors in a tissue. They are also regarded as the high-affinity cell surface receptors for many polypeptide growth factors, cytokines, and hormones.

It should be understood that, the activation of Tyrosine-kinase receptor is that  , the Inactive proteins within the cell bind to the phosphorylated tyrosine residues, the phosphate is transferred to the proteins, and the proteins become active.

Therefore, when the drug that specifically blocks the addition of phosphate groups to protein is used, it will definitely inhibit the activities of the Tyrosine-kinase receptor.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
