Answer:6CO2 + 6H2O -> C6H12O6 + 6O2
Explanation: Photosynthesis is a process by which green plants use energy from the sun to manufacture their own food from carbon dioxide and water. In the reaction, 6 molecules of water combines 6 molecules of carbon dioxide to form one molecule of glucose and 6 molecules of oxygen.
The equation for the reaction is shown below
6CO2 + 6H2O --> C6H12O6 + 6O2
In balancing a chemical equation, the total mass of the reactants must be equal to the total mass of the products because law of conservation of mass states that matter can neither be created nor be destroyed in an ordinary chemical reaction.
Answer:
The prolonged electrical depolarization of cardiac muscle cells -that occurs during contraction- is due primarily to the persistent influx of calcium ion
Explanation:
The action potential of the heart muscle is longer with respect to skeletal muscle (around 300 milliseconds), and this is due to the activity of calcium (Ca⁺⁺ ) in the intracellular compartment.
The initial depolarization of cardiac muscle fiber depends on the entry of sodium (Na⁺) into the cell. However, for the action potential to occur and be maintained, Ca⁺⁺ must increase its cytoplasmic levels, which depends on:
- The increase in intracellular sodium induces the release of Ca⁺⁺ from the sarcoplasmic reticulum.
- Calcium entry from the extracellular space through the voltage dependent Ca⁺⁺ channels.
- The entry of extracellular Ca⁺⁺ causes the release of more Ca⁺⁺ ions by the sarcoplasmic reticulum, further increasing its intracellular concentration.
This is how the ion that guarantees the duration of the action potential of the cardiac muscle cell is the Ca⁺⁺.
