Answer:
a) facilitated diffusion requires the use of a transport protein and energy in the form of ATP
Explanation:
Diffusion is defined as the movement of substances from high to lower concentration across a potential gradient. Facilitated diffusion and simple diffusion are two different types of diffusion.
Simple diffusion does not require energy while facilitated diffusion requires energy in the form of ATP. Facilitated diffusion is a type of passive transport in which transport protein and energy is used in the form of ATP that allow the movement of substances across the cell membrane. <u>There are majorly three types of proteins involved in facilitated diffusions such as channel proteins, carrier proteins, and gated channel proteins.</u>
<u>While in simple diffusion, pumps are used to move the substance across the membrane.</u>
Hence, the correct answer is "a".
Answer:
False
Explanation:
The autonomic nervous system supplies the organs of the body such as intestine, kidney etc and also controls the body functions.
It comprises of the sympathetic and parasympathetic nervous system.
SOME and not all visceral organs receive dual innervation(nerve supply) from both the sympathetic and parasympathetic divisions of the autonomic system and it’s dependent on the functions of the organ.
