The speed and direction of ion as they move in and out cell are determined by?
concentration gradient and electrochemical imbalances
What is the hydrogen ion gradient maintained by?
Carbon
What would increase the electrochemical gradient across a membrane?
Hydrogen ions are pumped across the membrane by carrier proteins of the electron transport chain
What process involves the chloroplast?
Photosynthesis (The chloroplasts in plant cells use solar energy to process nutrients.)
What is the energy of hydrogen ion gradient created across the inner mitochondrial membrane used to make?
The hydrogen falls down its electrochemical gradient, from an area of high concentration to an area of lower concentration, through the ATP synthase and provides the force to power this synthase and synthesize ATP.
What is the difference between diffusion and active transport refer to cell membrane and its properties?
Diffusion requires no energy as it follows the electrochemical gradient. Active transport requires energy (ATP), as it works against the electrochemical gradient.
What are the two forces that combine to produce an electrochemical gradient?
Chemical Force & Electrical Force
The speed and direction of ion as they move in and out cell are determined by?
concentration gradient and electrochemical imbalances
What is the hydrogen ion gradient maintained by?
Carbon
What molecule will form when hydrogen ions flow down the electrochemical gradient through ATP synthesis complexes in mitochondria?
Water
What is the source of the energy used in active transport?
The source of the energy used in active transport is the electrochemical gradient. Another possible source of energy for active transport is the breakdown of ATP molecules.
For what purpose does active transport use energy?
Active transport uses energy to move substances against a concentration or electrochemical gradient.
In photosynthesis the oxygen atoms from where are released as oxygen?
Oxygen released comes directly from the water used as a reactant. A plant enzyme splits water into protons, electrons and oxygen, with the electrons replenishing lost electrons in pigments, protons used to maintain the electrochemical gradient, and oxygen released as waste.
Why is a sodium potassium pump important in organisims?
Na/K ATPase is essential in maintaining the electrochemical gradient across the cell membrane. The electrochemical gradient generated by transporting Sodium out and Potassium in is used in secondary active transport, maintanence of osmotic balance, and most importantly, action potential generation and propagation in muscle and nerve cells.
Where does a cell release its ions?
A cell releases its ions into a PG (proper grammar) solution. This is achieved by transport through channels or with transporters. This process can be active (up the electrochemical gradient) or passive (down the electrochemical gradient), in the case of transporters. Channels always mediate passive transport. Either of these processes can be gated, for example, there are voltage gated channels.
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
In photosynthesis an H plus ion gradient froms across what?
across the thylakoid membrane
