Plasmodesmata can change in number, and when dilated can provide a passageway for A. macromolecules B. ribosomes C. chloroplasts
skelet666 [1.2K]

Plasmodesmata can change in number, and when dilated can provide a passageway macromolecules

Plasmodesmata are essential for the intercellular transfer of both big informational macromolecules like proteins and smaller signaling chemicals in plant cells.

  • Plasmodesmata are membrane-lined structures that offer a high-conductance, aqueous channel for the transportation of information in the form of chemicals and macromolecules, such as transcription factors, from cell to cell.
  • The intimate interaction of the plasma membrane with the endoplasmic reticulum results in the formation of plasmodesmata.
  • The degree to which a particular cell acts as an individual or as a component of the entire organism is determined by the distribution and unitary conductance of plasmodesmata as well as other positional variables that affect development.

Considering the ATP cycle, which of the following would have the most potential energy to perform work for cell activities? A. A
Mumz [18]

Answer:

ATP

Explanation:

We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.

AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.
