Answer:
Sunlight.
Explanation:
Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.
Answer:
opening of sodium channels
Explanation:
Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. Sodium channels are the founding members of ion channel super-family that includes voltage-gated calcium channels, TRP channels, voltage-gated, inward rectifying, and two-pore-domain potassium channels, and cyclic nucleotide-regulated CNG and HCN channels. When the neuron becomes stimulated the voltage gated sodium channels begin to open and the membrane potential begins to slowly depolarizes and sodium enters the cell down its concentration gradient.
I believe that secretion into the tubular fluid occurs when the principle cells in the Proximal convoluted tubule secrete H+ into the urine.
Tubular secretion is the transfer of materials from peritubular capillaries to the renal tubular lumen; it is the opposite process of reabsorption. This secretion is caused mainly by active transport and passive diffusion.
