Transcript

00:01 Here in this video we have different parts and first we will discuss the first part of the question which is as follows.

00:07 It is we have to fill in the blank that it is about insulin dash whereas glucargon dash right.

00:23 So we have different options and we need to choose the best ones.

00:26 So the first option is that insulin decreases the blood glucose concentration and it increases.

00:47 Blood glucose concentration right so the next part of the question is increases blood glucose it increases blood glucose and it decreases blood glucose concentration see part of the question is it removes blood glucose within the urine and it retained blood glucose in bloodstream.

01:58 So the d part of the question is it retains blood glucose in the bloodstream and removes in urine.

02:28 And the e part of the question is it decomposes blood glucose to water and carbon dioxide and it builds glucose into water plus carbon dioxide right so these are the options which given to us and we need to choose the correct one so the correct option is in in this is that it increases in the blood glucose stimulates and it lowers the blood glucose so the correct part is the b part as we all know that insulin is a hormone secreted by beta cells of pancreas, right? and it lowers which further lowers the blood glucose level by increasing the glucose intake, right? so the correct option over here is that it increases insulin increases the blood glucose level and it further on decreases the blood glucose concentration also we know that the glucose is quite important and the disease called diabetes is caused if there is increasing glucose level right so the normal blood glucose level is 100 is like 80 to 120 below or above this is a disease cause known as diabetes right so now we will talk about the second part of the question.

05:08 So the second part of the question is hormone secretion is controlled by which of the following? right.

05:23 So we have different option.

05:24 The first option is it is controlled by positive feedback mechanism.

05:41 The b part is it is controlled by negative feedback mechanism.

05:56 The c part is that it is controlled by reflex loop mechanism the part is it is controlled by the demand of local organs the part is it does not control endocrine glands produced hormones all the time whenever it active like it is it doesn't control right so the correct option over here is negative feedback mechanism as we know that hormone -level is primary controlled by negative feedback mechanism which further in which rising levels of hormone inhibits its further release right so if there is any kind of rising level then the hormone inhibits the further release and it is like for the safer side if any hormone is secreted more than the requirement, then it is controlled by negative feedback.

07:51 So the correct option over here is b part, that it is controlled by negative feedback mechanism.

08:04 Right.

08:05 So now we will discuss about the third part of the question, which states that which hormone exerts its, which hormone exerts its, which hormone exerts its effect on reproductive organ right so what we have we have different option it is a dh that is anti -diarotic hormone b option is f sh that is fosch that is folicill simulating hormone c is prf d is a.

09:06 C .t .h.

09:08 Which is endrinocotropic hormone.

09:14 E.

09:18 Is norepine ferrine.

09:23 Right.

09:25 So we have to tell the effect of it on the reproductive organ, right? so we all know that phyllis stimulating hormone that is f .s .h...
