Question

1. The ability of a specific tissue or or organ to respond to the presence of a hormone is dependent on ________.

A. the presence of the appropriate receptors on the cells of the target tissue or organ

B. The location of the tissue or organ with respect to the circulatory path

C. The membrane potential of the cells of the target organ

D. nothing----all hormones of the human body are able to stimulate an and all cell types because hormone are powerful and nonspecific

I picked A, is this correct?

2. Steroid hormones exert their action by _________.

A. entering the cell and activating mitochondrial DNA

B. Activating the hypothalamic release of regulating hormones

C. Entering the nucleus of a cell and initiating or altering the expression of a gene

D. Binding the cell receptors and initiating cAMP activity

I picked C is this correct?

Answer 1

1. The ability of a specific tissue or or organ to respond to the presence of a hormone is dependent on the presence of the appropriate receptors on the cells of the target tissue or organ(A)

Due to presence of receptors the ability of specific tissue responds to specific hormones

Hormones are specific.

Hormones are not responded due to circular path.

Membrane potential does not play any role in hormone response.

2. Steroid hormones exert their action byEntering the nucleus of a cell and initiating or altering the expression of a gene.(C)

They do this by binding cytoplasmic receptors in cells.
