An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. nucleus.
Competitive inhibition can be overcome by increasing the concentration of substrate while uncompetitive and noncompetitive inhibition cannot. Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity.
The answer is <span>0.132606 amu.</span>
The mass defect (Δm) is the total mass of protons and neutrons minus the mass of the atom.
<span>mass of an oxygen-16 atom: 15.994914 amu
mass of a proton: 1.00728 amu
mass of a neutron: 1.00866 amu
</span>
An oxygen atom has 8 protons and 8 neutrons. Therefore:
Δm = 8 · 1.00728 + 8 · 1.00866 - <span>15.994914 = 8.05824 + 8.06928 - 15.994914 = 0.132606 amu
</span>
Answer:
They produce the:
• Tropic hormones (Thyroid stimulating hormone, Adrenocorticotropic hormone ACTH, Luteinizing hormone LH and Follicle-stimulating hormone FSH).
• The growth hormone and
• Prolactin.
Explanation:
The pituitary gland, found just below the hypothalamus consists of an anterior and posterior part, which release hormones which are either proteins or polypeptides
The secretion of these hormones are stimulated by chemicals produced by the hypothalamus and transported to the pituitary in the bloodstream.
The anterior pituitary glands hormones consists of several tropic hormones that regulates the activities of the other endocrine glands(through homeostatic mechanisms); also the growth hormone and prolactin.
Answer: The correct answer is macrophages
Explanation:
Macrophages are examples of phagocytes, and they engulfs pathogens (disease-causing organisms such as viruses, bacteria) by pulling them into their vacuoles and digesting them completely.
Macrophages, and Other like T-cells, B lymphocytes and natural killer cells all help in the BODY DEFENCE. But unlike macrophage, others exert their function through a different mechanism.
