Caffeine cause dose dependent prominent increase in force of contraction and period of contraction of muscle
<u>Explanation:</u>
Caffeine is widely used in foods and drinks. Its long time use can effect central nervous system include lethargy memory, sleep disorder and anxiety.
Increase in concentration of calcium ion will result increase number of power stroke and force for contraction. However latent period and relaxation period are unaffected by caffeine. Increase in concentration of calcium ion will result increase number of power stroke and force for contraction.
Because of calcium ion release in skeletal muscle, caffeine causes peripheral manifestation such as hyper-reflexia, muscle twitching etc.
High amount of caffeine leads to increase in release of Ca2+ from sarcoplasmic reticulum. It increases tension development in single tetanic contraction and re-initiate maximum tension in fatigue single myofibre by restoring Ca2+ release from sarcoplasmic reticulum to non-fatigued levels.
Answer:
The correct answer is option d.
Explanation:
Chemical cycling illustrates the systems of concurrent circulation of elements between other states, compounds, and substances, and then return to their original state, which takes place in space, and on many objects in space comprising the Earth.
Chemical cycling of the nutrients (inorganic) is needed to maintain the conservation of nutrients on Earth. The chemical cycling of nutrients in a natural system requires a pool for the elements, the activities done by human beings, the biotic community and its food chains, and an exchange pool from which producers extract their nutrients. All the mentioned factors are associated with affecting a chemical cycling in exception to the input of geothermal energy.
