The correct answer is "active transport is ATP dependent whereas in passive transport molecules use kinetic energy to move across the membrane." in active transport cells use molecules embedded on the cell membrane called carriers in the presence of energy. cells use energy and carriers because molecules must move against concentrated gradient inside the cell. on the hand, passive transport is a process by which molecules move from the region of high concentration to the region of low concentration across plasma membrane until balance is obtained on both sides of the membrane. once equilibrium has been achieved in passive transport the movement of molecules stops.
Answer:
The correct answer is - option D. gate- control theory of pain.
Explanation:
Gate control theory of pain suggests that non painful stimulus that inhibits or closes the the gates for the stimulus of the pain. This mechanism helps in the prevention of of the pain sensation to travel to the CNS. It is also refereed as the doorway in the spinal cord that is passed from the signals.
Thus, the correct answer is - option D. gate- control theory of pain.
Answer:
The answer is A because it erodes rocks away over time
Explanation:
A
The integumentary system (skin) has been called a membrane and an organ but, it is generally considered a system because it has organs that work together as a system. It is sometimes considered an organ because it contains several types of tissues and a membrane and it covers the body.
Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
