Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
<h2>Answer:</h2>
B. Decreases
<h2>Explanation:</h2>
According to the golden rules of business when the supply increases with the demand, the prices are reduced by the suppliers because manufacturing cost of a single product is very costly as compared to the manufacturing cost of a bulk of products. The same rule is applied to the purchaser if he purchases bulk of products, the cost will decrease.
I believe option B would be the correct choice because, without a catalyst, the reaction will be either too slow or will not happen at all as it would not acquire a fitting activation energy for the reaction.
If you would like to know why the other options are incorrect, please read on:
Option A is incorrect because since proteins are specific in nature, so other protein cannot be replaced, for some other chemical reaction.
Option C is not correct it is a genetic defect that the protein does not form, and all cells are genetically identical, a reaction cannot take place in any parts of the body.
And finally, option D would be wrong because if a forward reaction does not take place, a backwards reaction will not occur.
I hope this answer has helped, and I apologise if somehow this answer finds itself to be incorrect. Good luck on your quiz or homework. :)
<span>The correct answer is gene. Genes are carriers of the genetic material that get transferred from a parent to an offspring after sexual reproduction. If the proteins and the codes are synthesized badly, things like genetic disorders are created and these are diseases that get transferred from a parent to a child like Huntington's disease or anything similar.</span>
Answer:
The correct answer is hypophysis or pituitary.
Explanation:
The pituitary gland is at the size and shape of a pea and is also known as the master gland because it controls and stimulates the regulation of other endocrine glands. The pituitary gland is itself an endocrine gland which secretes its hormone directly in the blood.
Some hormones released by pituitary that stimulate other endocrine gland are adrenocorticotropic hormone (ACTH) which stimulate the adrenal gland to release cortisol. FSH and LH hormone that stimulate testes and ovary in male and female, Thyroid-stimulating hormone (TSH) which stimulate thyroid gland, etc. Therefore the right answer is pituitary.
