Which of the following is not correct regarding competitive inhibition?

Options:
A The inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme.
B They cannot be used to control bacterial pathogens.
C Inhibition of succinic dehydrogenase by malonate which closely resembles the substance succinate in structure is an example of it.
D Substrate cannot bind in such type of inhibition thus enzyme activity declines.

The correct answer is:
They cannot be used to control bacterial pathogens.

Solution:
Competitive inhibition is a type of inhibition process observed for enzymes. In this, the competitive inhibitor closely resembles the structure of substrate and binds to the same site of the enzyme. Thus, blocking the binding of the substrate and slowing down the enzyme activity. Competitive inhibition is often used in the control of many bacterial pathogens.

Which of the following is not involved in the endocrine secretion?

Options:
A Leydig cell
B Lutein cell
C Para-follicular cells of thyroid
D Kupffer cells

The correct answer is:
Kupffer cells

Endocrine glands are ductless glands as these glands pour their secretions i.e. hormones directly into the blood. Examples are pituitary gland, thyroid gland, parathyroid gland, adrenal gland, etc. Some glands are heterocrine glands as they have endocrine and exocrine cells both. Examples are gonads and pancreas. Hormones are secreted by cells of endocrine glands. Example, para- follicular cells or C cells of thyroid secrete Calcitonin. Similarly, Leydig cells of testes secrete testosterone hormones and Lutein cells of Corpus luteum (this is formed after the rupture of mature ovarian follicle) secretes progesterone.
Kupffer cells are the macrophages found in sinusoid of the liver.

Which of the following is not isostructural with $\mathrm{SiCl}_4$ ?

Options:
A $\mathrm{NH}_4^{+}$
B $\mathrm{SCl}_4$
C $\mathrm{SO}_4^{2-}$
D $\mathrm{PO}_4^{3-}$

The correct answer is:
$\mathrm{SCl}_4$

Solution:
$\mathrm{SCl}_4$ is not isostructural with $\mathrm{SiCl}_4$ because it shows a square planar structure due to the repulsion between lone pair and bond pair of electrons.
$\mathrm{SO}_4^{2-}, \mathrm{PO}_4^{3-}, \mathrm{NH}_4^{+}$shows tetrahedral structure because of $s p^3$ hybridisation.

Topic: Biology, Environmental Issues, NEET, NEET 2015 (Phase 1)
Which of the following is not one of the prime health risks associated with greater UV radiation through the atmosphere due to depletion of stratospheric ozone?

Options:
A reduced immune System
B damage of eyes
C increased liver cancer
D increased skin cancer

The correct answer is:
increased liver cancer

Solution:
Ozone depletion in the atmosphere causes increased UV radiation towards the Earth surface. Exposure to higher concentration of UV rays can lead to mutation resulting in skin cancer. It can also cause permanent damage to the eyes by destroying the retinal cells. UV rays have been found to cause mutational changes in the immune cells and reducing the immune system.
Liver cancer occurs due to abnormal growth of liver cells majorly due to excessive consumption of alcohol and drugs but not due to UV rays.
