What type of cell transport is used by chloroplasts to make hydrogen ions move against their concentration gradient?
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.
What is the process that allows oxygen to pass from the tracheoles to the body cells?
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.
What is The process by which small molecules pass through a membrane by moving from an area of high concentration to an area of low concentration is?
This process is called passive diffusion or simple diffusion. It does not require energy input and relies on the concentration gradient to drive the movement of molecules across the membrane.
The movement of glucose molecules across a plasma membrane from an area of lower glucose concentration to an area of higher glucose concentration occurs due to?
active transport, specifically through a process known as secondary active transport or cotransport. This process relies on the use of energy generated by the concentration gradient of another molecule, usually sodium ions, to drive the movement of glucose against its gradient.
Is simple diffusion saturable?
No, simple diffusion is not saturable because it does not involve specific carrier proteins or channels that can become saturated as concentration increases. Instead, it is a passive process that relies on the concentration gradient of molecules for movement across a membrane.
What name is given to the process by which substances pass into or out of a cell from an area of higher concentration to an area of lower concentration?
diffusion
Photosynthesis relies on gas defusion briefly describe the process of gas diffusion and explain what is meant by concerntration gradient?
well concentration gradient is when both sides are evened out and if both sides are evened out then they are withconcentration gradient but when they are not evened they are against concentration gradient!

How do molecules travel in passive transport when moving up their concentration gradient?
In passive transport, molecules move up their concentration gradient without using energy. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration. This movement is driven by the principle of diffusion, where molecules spread out to achieve a balance.

Why does osmosis not an active transport?
Osmosis is a passive transport process because it does not require energy to move molecules across a semipermeable membrane. It relies on the concentration gradient of solute particles to drive the movement of water molecules from an area of high concentration to an area of low concentration. In contrast, active transport requires energy in the form of ATP to move molecules against their concentration gradient.
How does passive transport move substances across a cell membrane in the direction of their concentration gradient?
Passive transport moves substances across a cell membrane in the direction of their concentration gradient without requiring energy input from the cell. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, facilitated by protein channels or carriers in the cell membrane.
Is energy required to move molecules from a high concentration to a low concentration?
Yes, energy is required to move molecules from a high concentration to a low concentration. This process is known as passive transport and it relies on the kinetic energy of the molecules themselves to move across the concentration gradient.
Why is facilitated diffusion not considered an active transport process?
Facilitated diffusion is not considered an active transport process because it does not require energy input from the cell. Instead, it relies on the assistance of transport proteins to move molecules across the cell membrane, following their concentration gradient. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
