<span>Once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accommodate the product. This structural change lowers the activations energy and increases the rate of the reaction. The active site changes its shape until an enzyme-substrate complex is formed and activated.</span>
Answer:
c. plantae
the organism described does not move and makes its own food. which means it is a plant. kingdom animalia is mostly animals. kingdom fungi is mostly fungi (which it could be). kingdom plantae is plants. and archaebacteria is bacteria. we can cut out A and D. go back to the question and it says "most likely" so with this we know it is c.
Answer:
b. They are carried throughout the body in the bloodstream, and each hormone affects target cells that have receptors for it.
Explanation:
Hormones are secreted by hormonal glands after they get signals to secrete or release the hormone. Then these hormones are carried by the bloodstream to their destination. Each hormone has its target organ or tissue which do not response to other hormones because it the cells in those tissue have specific receptor which binds to specific hormones.
For example, luteinizing hormone in male is produced by the pituitary gland which reach to the testis through blood and influence the Leydig cell to release testosterone. So Leydig cells have receptors for LH not for insulin hormone so it binds specifically to LH hormone. So the correct answer is b.
