Question

How do cells get energy that is needed for active transport processes?

Answer 1

Solution-How do cells get energy that is needed for active transport processes?

Answer-Any live cell is an active, dynamic system. It occurs in the conversion of energy, synthesis, decay and transfer of substances.

These processes are called metabolism or metabolism.

In organisms simultaneously occur the processes of two types: synthesis and splitting of substances. The combination of the reactions of the synthesis of complex organic substances from the simpler is called assimilation.

These processes are called plastic exchange. During the plastic metabolism from the substances from the environment, substances specific to this organism (carbohydrates, fats, proteins are synthesized.). Synthesized substances are used to build new cells and updating cellular structures. The synthesis processes go with the cost of energy that is concentrated in ATP (adenosine trifosphoric acid) molecules. Splitting of complex organic substances and turning them into.German exchange products - carbon dioxide, water, ammonia - called

dissimulation or catabolism. The responses of catabolism are accompanied by the release of energy, the part of which is lost, scattering in the form of heat, and part is inhibited in the macroergic phosphate bonds of ATP molecules. ATP is a universal keeper and energy carrier in the cells of all organisms. A combination of reactions of splitting complex compounds accompanied by emission and the synthesis of ATP molecules is called energy exchange.

Assimilation and dissimilation are used in cells. Energy released in cells in the process of dissimulation is used during assimilation organic substances split in the process of dissimulation.

For any manifestations of vital activity requires energy. It is required for biochemical synthesis processes, for all types of movement, including muscular, for transmission of nervous pulses. Energy is also required to form heat and maintain a constant body temperature in birds and mammals.

Energy is also spent on the processes of active transfer of substances through the plasma membrane (into the cell and from the cell), and a very significant part of the cell energy resources is consumed.
