Answer:
The inflow of sodium ions.
Explanation:
The generation of the action potential requires the change in the membrane potential of the cell. This membrane potential is maintained due to the unequal distribution of the ions.
The cell potential of the cell is -70mV and maintained due to the presence of potassium ions. The depolarization occurs due to the influx of the sodium ions and results in the change in the membrane potential upto +30mV. The neurotoxin that interferes with depolarization process might affect the sodium ions uptake.
Thus, the answer is inflow of sodium ions.
Answer:
(a) Allow movement in only one plane/direction (that is extension or flexion)
(b) The skeletal system also produces blood cells in their bone marrow
Answer:
NADH
Explanation:
Electron carriers such as NADH produced during glycolysis and the Krebs cycle pass their electrons to the electron transport chain, which results in synthesis of a lot of ATP.
Homeostasis is the equilibrium of a cell.
Autotrophs make their own food through photosynthesis.
Mitochondria undergoes cellular respiration and is often referred to as the "powerhouse of the cell".
