Is water an active or passive transport?
Water can use both passive and active transport mechanisms. Passive transport involves movement of water molecules across a membrane without the need for energy, while active transport involves the use of energy to move water molecules against their concentration gradient.
Is pushing a cart through a store more like active transport or passive transport Why?
Pushing a cart through a store is more like active transport because it requires energy and effort to move the cart against resistance, such as friction or gravity. Active transport involves moving substances across a membrane against a concentration gradient, which also requires energy. In contrast, passive transport occurs naturally without energy input, like a ball rolling downhill. Therefore, the act of pushing a cart involves an active process similar to active transport.
Are fats absorbed by active transport or passive transport?
Fats are absorbed mainly by passive transport in the small intestine. This process involves the diffusion of fatty acids and monoglycerides across the intestinal epithelium and into the bloodstream without the need for energy input.
How can a cell transport a substance from lower to higher concentration?
A cell can transport a substance from lower to higher concentration through active transport, which uses energy to move molecules against the concentration gradient. This process typically involves the use of specialized proteins in the cell membrane to pump the molecules against the concentration gradient.
What separates active transport from passive transport?
Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.
What involves two active transport processes coupled together?
Cotransport
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.

What is the process that requires the use of energy to move materials across a membrane?
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
Active transport requires energy because it usually involves the movement of what substances?
Molecules

Is it true that the cell mechanism of active transport involves the transport of insoluble chemicals across the membrane with protein acting as the carrier?
yes
How can active transport differ from passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
How does facilitate transport differ from active transport?
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
Does active transport require transport proteins?
Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.

Describe the two methods of active transport?
Active transport involves the movement of molecules against their concentration gradient, requiring energy input. Two methods of active transport include primary active transport, where energy from ATP is directly used to move molecules, and secondary active transport, where the movement of one molecule down its gradient provides energy to transport another molecule against its gradient.
