Answer:
it could not depolarize because the cell cannot become more positively charged.
Explanation:
When sodium gates open, depolarization occurs, changes the charge of the ion from negative to positive. Therefore, if the sodium channels no longer open, the flow of sodium into the cell that changes the charge from - to + and depolarization would not occur.
Answer:
Adenosine triphosphate (ATP) is an essential biomolecule that stores and provides chemical energy in living organisms. It acts as a "currency" for energy transfer within cells. Let's break down its structure and function:
1. Structure: ATP is composed of three main components:
a. Adenine base: It's a nitrogen-containing molecule that serves as a building block of nucleotides.
b. Ribose sugar: This is a five-carbon sugar molecule that is bonded to the adenine base.
c. Phosphate groups: ATP has three phosphate groups attached to the ribose sugar.
2. Energy Storage: The energy in ATP is stored in the bonds between the phosphate groups. These bonds are high-energy bonds, meaning they contain a lot of potential energy.
3. Energy Release: When the cell needs energy, ATP can be hydrolyzed, or broken down, by removing one phosphate group. This results in the formation of adenosine diphosphate (ADP) and an inorganic phosphate molecule. The breaking of this bond releases energy that can be used by the cell for various processes.
4. Recycling ATP: ADP can be further hydrolyzed to form adenosine monophosphate (AMP) by removing another phosphate group, but this reaction releases less energy compared to the conversion of ATP to ADP. ATP can be regenerated by adding a phosphate group back to ADP through a process called phosphorylation. This recycling process allows ATP to continuously provide energy within the cell.
To summarize, ATP is a molecule that stores and provides chemical energy in cells. It consists of an adenine base, ribose sugar, and three phosphate groups. Energy is released when ATP is converted to ADP by breaking the bond between the second and third phosphate groups. ADP can be further converted to AMP, but with less energy release. Through phosphorylation, ADP can be converted back to ATP, ensuring a continuous supply of energy for cellular process
