Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
Answer:
False
Explanation:
Ethyl alcohol is formed only during alcoholic fermentation and in lactic acid fermentation lactic acid is formed
Answer:D
Explanation:
Respiration is the process of taking in oxygen and release of Carbondioxide in the lungs(breathing),the absorption of the oxygen in the alveolar, into the blood stream for distribution to tissues , the combustion of the metabolites(glucose,amino acids, and fatty acids and glycerol)with the inhaled oxygen to give energy as ATPS and water vapour.
Answer:
During transcription, active genes are brought to the periphery of a territory.
During replication, DNA is collected in regions where replication machinery is located.
Transcription continues even as a cell has entered S-phase.
Explanation:
The statements given above are correct. The periphery territory is inter specific behavior exclusion in the cells. It receives active genes during transcription and intimidates the behavior. The DNA is collected during replication in the regions where there is replication machinery. The transcription in cells continues even if it has entered S-phase.
