Answer:
Humans get there energy primarily from glucose I believe. We break down glucose to get ATP (Adenosine Triphosphate) which is then used to supply energy to our cells in order to function.
Explanation:
Answer:
The correct answer is - option d.
Explanation:
Myasthenia gravis is an autoimmune condition in which nerve endings are targeted due to the body produces antibodies against receptors of nicotinic acetylcholine which results in less or no functioning of nerve endings of motor neurons mostly.
Options A, B, and C all three conditions are all due to an increase in muscle movement which is not the case as it causes weakness in the muscles due to less functioning in motor end plates.
Answer:
the correct sequence of the events happened during nerve impulse is (d): 2,1,4,3
Explanation:
Originally K+ ions remains inward the membranes while Na+ ions remains outward to maintain a resting potential of membrane.
Upon stimuli Sodium channels open on membrane and Na+ diffuses inward leading to the depolarization of membrane that is it becoming more positive due to Na+ and K+ ions.
To regain it polarized state or in repolarization state Potassium channels open and K+ begun to diffuse outward while Sodium channels gets closed and Na+ ions remains inside the membrane.
Potassium channels are not efficient as compared to Sodium Channels, so an excess amount of K+ion move outward so Hyperpolarization state achieved.
As the both ions are on the wrong side and will not be available for the next nerve impulse. Hence in Refractory period by the help of Na+/K+ pum, both ions move back to their original place and membrane achieve its resting membrane potential state.
Answer:
ATP is an output in cellular respiration
Explanation:
Cellular respiration is a process using oxygen and a sugar called glucose, and converting into ATP, or the energy plants use to function.
Since ATP is what is outputting from the product of oxygen and glucose, it can not be inputted, therefore it is only an output.
