Answer:
This question lacks options, the options are:
A) The free energy of the reactants is greater than the free energy of the products.
B) The equilibrium constant of the reaction is much greater than 1.
C) The shape and charge of the substrates are compatible with the active site of the enzyme.
D) The concentration of the enzyme inside living cells is greater than the concentration of substrate.
The answer is C
Explanation:
An enzyme is a proteinous molecule that increases the rate of reaction of a biochemical reaction in living organisms. However, a protein molecule contains amino acids which makes up it's primary structure. An enzyme performs it action by binding to it's substrate using it's active site.
An enzyme is substrate specific because the shape and charge of the substrates are compatible with the active site of the enzyme, where the reaction occurs. This means that an enzyme will not bind to any substrate that its active site does not recognize
Im pretty sure its A, I know this because the question is asking which on is an insertion for the original DNA sequence. A inserts a C in between the G-G.
Cells use cyclins and cyclin-dependent kinases to control the cell cycle. Different combinations of cyclin/CDK start the cell cycle at different checkpoints and monitor the cycle for quality control. In G1 stage, the cell is growing and preparing to replicate DNA. DNA replication occurs in the S stage . In G2 stage , the cell takes inventory to ensure it is ready to proceed to mitosis . If the spindle apparatus malfunctions, the cycle won’t proceed to cytokinesis.
Each stage of the cell cycle has related cyclins that help the progression of that phase. Cyclins bind to cyclin-dependent kinases and activate them. The kinases are therefore able to phosphorylate particular protein and activate or deactivate them appropriately to progress the particular cell cycle stage. P53 tumor suppressor protein proteins help regulate this progress at each checkpoint. They do so by activating CDK inhibitors when required (such as when there is damage to the cells DNA).
