Answer:
bio diversity is important for our planet
Answer: A (ATP only)
Explanation:
Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.
Answer is ATP only
The reaction will occur naturally. Positive voltage means it is a working cell.
Answer:
In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.
Explanation:
Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.
-
Na⁺ is a predominantly extracellular cation.
- K⁺ has a high intracellular concentration.
This distribution occurs when the membrane potential is at rest, with a negative intracellular value.
Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.
While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.
