Answer:
Intracellular receptors are located within a cell and bind to molecules that cross directly through the membrane. Membrane receptors are located in the membrane, bind to molecules that cannot cross it, and transmit the signal to the cell interior by changing shape.

Answer:
Energy:
The rate of movement per unit time of an object relative to all the other objects in the universe.
Generally we have it relative to the road on earth. For instants, you could travel 80 miles per hour relative to the road.
 
        
                    
             
        
        
        
Answer: By losing its two outermost electron 
Explanation:
Calcium is a element that belongs to group 2 in the periodic table. It has an atomic number of 20, and an electronic configuration of 2, 8, 8, 2.
 Hence, to form an octet structure, it gives off its two electrons as shown below:
Ca <----> Ca2+ + 2e-
Thus, by losing its two outermost electrons, a positively charged calcium ion (Ca2+) is formed
 
        
                    
             
        
        
        
Answer:
False.
Explanation:
NADP does not  convert  testosterone to estradiol. This oxidation  is done by a steroid   17-a-hydroxysteroid dehydrogenase.
This oxidation  is essential for stability of hormone: it helps to regulates the elevation of Testosterone in women,subduing the manifestation of male sexual characteristics,
and 
for preventing autoimmune diseases.
<u>The oxidation involved two basic  steps of  reaction, controlled by two different enzymes.</u>
 
<u>NADP is a Co- factor,  when in reduced form( NADPH) is used in Calvin cycle, of light independent reaction of photosynthesis, and in Nucleic acid and triglycerides synthesis</u>. 
It has nothing to do with conversation of Androgen( testosterone  to Estradiol.
