Is the concentration gradient active or passive in cellular transport processes?
The concentration gradient is a passive force in cellular transport processes.
What is the relationship between the electrochemical gradient and the concentration gradient in cellular transport processes?
The electrochemical gradient is a combination of the electrical gradient and the concentration gradient. It influences the movement of ions across cell membranes during cellular transport processes. The concentration gradient refers to the difference in the concentration of ions or molecules inside and outside the cell, while the electrical gradient refers to the difference in charge across the cell membrane. Together, they determine the direction and rate of ion movement in cellular transport processes.
Is hydrogen gradient across the mitochondrial inner membrane a cellular energy currency?
ATP molecules are essentially cellular energy currency. The hydrogen gradient (or proton gradient as it is technically called) is responsible for the functioning of a protein complex called ATP synthase which in turn is responsible for the synthesis of ATP molecules. Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.
What is A transporter protein that carries a substance across a cellular membrane against its concentration gradient?
pump
A transporter protein that carries a substance across a cellular membrane against its concentration gradient?
pump
Transporter protein that carries a substance across a cellular membrane against its concentration gradient?
pump
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport is the process that requires cellular energy to move a substance against its concentration gradient. This process uses ATP to pump molecules across the cell membrane, creating a concentration gradient where the molecule is more concentrated on one side of the membrane than the other.
What is the scientific name for power from convection currents?
Trans-density migration motion via gravitational field gradient energy transferal.
What is the migration of phagocytes and white blood cells to an inflamed area along a chemical gradient is called?
This process is called chemotaxis. Phagocytes and white blood cells are attracted to the site of inflammation by chemical signals released by damaged cells. Chemotaxis helps these cells locate and eliminate pathogens and damaged tissue in the inflamed area.
The generation of ATP by the movement of protons down their concentration gradient occurs in?
The generation of ATP by the movement of protons down their concentration gradient occurs in the electron transport chain during cellular respiration. This process is called chemiosmosis. The movement of protons creates a proton gradient across the inner mitochondrial membrane, which drives ATP synthesis by ATP synthase.
What is the role of hydrogen ion gradient used for in cellular respiration in the mitochondria?
The hydrogen ion gradient is used to drive ATP synthesis. 32 to 34 molecules of ATP are produced. The hydrogen ion gradient is the result of NADH in the electron transport system of the mitochondria.
Which is the process that uses oxygen and an electron gradient to make ATP water and carbon dioxide?
aerobic cellular respiration
