active transport
The movement of hydrogen ions across a mitochondrial membrane.
Chemiosis, also known as chemiosmosis, is a process that occurs during cellular respiration and photosynthesis. It involves the movement of ions across a membrane to generate ATP, the energy currency of the cell. Chemiosis relies on an electrochemical gradient to drive the production of ATP.
Chemiosmosis is the process by which protons are transported across a membrane to generate ATP. In cellular respiration, chemiosmosis occurs in the inner mitochondrial membrane during oxidative phosphorylation. Protons are pumped across the membrane, creating an electrochemical gradient that drives ATP synthase to produce ATP.
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
The process responsible for the transport of oxygen and carbon dioxide across the alveolar membrane is called diffusion. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. This process is driven by differences in partial pressures of these gases on either side of the membrane.
active transport
The electrons moving across the inner membrane in mitochondria come from the oxidation of nutrients, such as glucose, during the process of cellular respiration. These electrons pass through the electron transport chain, generating a gradient of protons across the inner membrane that is used to produce ATP through a process called oxidative phosphorylation.
The movement of hydrogen ions across a mitochondrial membrane.
The process responsible for involving an antiport carrier moving solutes in opposite directions across a cell membrane is called countertransport. This process utilizes the energy stored in the electrochemical gradient of one solute to drive the movement of another solute in the opposite direction.
Chemiosis, also known as chemiosmosis, is a process that occurs during cellular respiration and photosynthesis. It involves the movement of ions across a membrane to generate ATP, the energy currency of the cell. Chemiosis relies on an electrochemical gradient to drive the production of ATP.
You are describing active diffusion.
The charge differences across the inner mitochondrial membrane are used to generate ATP through a process called chemiosmosis. Protons are pumped across the membrane, creating a proton gradient. As protons flow back across the membrane through ATP synthase, ATP is produced. This process is essential for providing energy to the cell.
The process that moves oxygen across the cell membrane is called simple diffusion. Oxygen molecules move from an area of high concentration to an area of low concentration without the need for energy input. This process helps maintain the balance of oxygen inside and outside the cell for cellular respiration.
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
