Out of the following given choices;
<span>A. </span>The sodium channels would open and close randomly, regardless of the presence of light.
<span>B. </span>The sodium channels would remain closed in the light and the dark, even when cGMP decreases after light stimulation.
<span>C. </span>The sodium channels would remain open in the dark and close rapidly to the light.
<span>D. </span>The sodium channels would remain open longer, even when cGMP decreases after light stimulation.
The answer is D. cGMP maintain the sodium channels open when there is no light stimulation. This ensures that there is high intracellular Ca2+ concentration due to the Na+/Ca2+-K+ exchanger. When cGMP is hydrolyzed in light stimulation cascade, the channels close causing hyperpolarization of the rod cells.
Answer:
a) 1:B; 2:C; 3:A; 4:B; 5:C
Explanation:
Primary fuel source for tissues can be defind as the source of energy required for proper functioning of different tissues.
Brain consider glucose, a form of sugar to fuel cellular activities. Food provide glucose energy and through blood brain cell recieves the glucose.
Primary fuel source in resting skeletal muscle are glucose, fatty acids, amino acids that depends on the muscular activity and further participate in the citric acid cycle for oxidation to CO2.
Primary fuel of heart is fatty acids which carry important beta-oxidation equipment and serve as fuel for heart functions.
Glucose is the primary source of energy for adipose tissue which on breakdown contribute to ATP synthesis.
Liver utilises fatty acids, glucose and amino acids as primary fuel source. When glucose is present in high quanity, it converted into fatty acids.
Hence, the correct option is a) 1:B; 2:C; 3:A; 4:B; 5:C
Answer:
particle movement in hotter waters will be higher than particle movement in cold water. I dont have exact numbers because I did not do the expirement.
Explanation:
thereby decreasing the pH and increasing the acidity of water. pH is a measure of acidity or basisity (alkalinity) of a solution.
Answer:
The Coriolis effect makes storms and winds swirl clockwise in the Southern hemisphere and counterclockwise in the Northern Hemisphere.
