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.
<span>Rough endoplasmic reticulum is found throughout the cell and produces cellular membranes by providing membrane proteins and phospholipids to its own membrane. It's called "rough" because its outer surface is dotted with ribosomes.</span>
It's responsible for motor control and balance and coordination of body and muscles.
Without photosynthesis, there wouldn't be any sugar or o2 which kick off the respiration reaction. Without respiration, plants would use up all the CO2 and die to extinct.
<h3>What is photosynthesis?</h3>
The photosynthesis is a process that occurs in the chloroplast organelle of the plant cells. The typical light reaction of the photosynthesis takes place inside the thylakoid membrane of the chloroplast.
The chief reactants such as water and carbon dioxide participate in the reaction. The water gets oxidized in the reaction to release the oxygen as a product. The carbon dioxide get reduced.
Thus, Photosynthesis requires the products from respiration, and respiration requires the products from photosynthesis.
