active transport
this is called active transport, bc it uses energy and goes against the concentration gradient
active transport, where energy is used to move molecules against their concentration gradient to maintain a higher concentration in a particular area. This process is essential for cell functioning and maintaining homeostasis in living organisms.
The relative concentration of molecule X determines the direction and rate of diffusion; if there is a greater concentration gradient of molecule X, more ATP will be used to facilitate the diffusion process. ATP is used to power certain transport proteins that move molecules against their concentration gradient, so the amount of ATP used is dependent on the concentration gradient of molecule X.
When a substance moves from an area of low concentration to an area of high concentration, it is moving against its concentration gradient. This process typically requires energy, as it is not a passive movement. Such transport mechanisms include active transport, where cellular energy (like ATP) is used to facilitate the movement. In contrast, substances usually move from high to low concentration naturally, which is known as moving down the concentration gradient.
A concentration gradient forms when there is a difference in concentration between one place and another.
Active transport is the type of transport in which a cell moves substances against their concentration gradient, requiring energy to do so. This process helps maintain the internal balance of substances within the cell.
Active transport is used to move a molecule from a region of low concentration to a region of high concentration. This process requires energy input in the form of ATP to pump the molecule against its concentration gradient.
Active transport is used to move a molecule from a region of low concentration to a region of high concentration. This process requires the input of energy, typically in the form of ATP, to move molecules against their concentration gradient.
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
Mitochondria utilize active transport to move hydrogen ions (protons) against their concentration gradient. This process primarily occurs during oxidative phosphorylation, where the electron transport chain pumps protons from the mitochondrial matrix into the intermembrane space. This creates a proton gradient, which is subsequently used by ATP synthase to generate ATP as protons flow back into the matrix.
Chloroplasts utilize active transport to move hydrogen ions against their concentration gradient. This process relies on energy, typically derived from ATP, to pump protons into the thylakoid lumen during photosynthesis. The resulting gradient of hydrogen ions is then used to drive ATP synthesis through chemiosmosis, ultimately supporting the production of energy-rich molecules.
Glucose hitches a ride with sodium through a symporter protein on the cell membrane. This process is known as secondary active transport, where the energy stored in the sodium gradient is used to transport glucose into the cell against its concentration gradient.
