Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.
Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
Available oxygen
Available oxygen is the amount of oxygen present at a specific time that can be used in aerobic cellular respiration.
Aerobic cellular respiration is a metabolic process that occurs within the cells of organisms. In this process, oxygen is used in the mitochondria to chemically convert organic molecules such as glucose into adenosine triphosphate (ATP), with the release of water and carbon dioxide as waste products. Aerobic cellular respiration results in a larger amount of energy (ATP) which is used by the cell to perform its activities.
Answer:
Electrons are the negatively charged particles of an atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The mass of an electron is almost 1,000 times smaller than the mass of a proton.
Explanation:
I hope this helped!
Answer:
Yes.
Explanation:
Energy can always be transformed from one form to another form.
E.g. Throw a ball in upward direction ,so it will have some kinetic energy due to its mass and velocity. At some height ball will stop and will start coming down.
