What else can I help you with?
What are 2 situations which active transport would be required?
well if the active transport was not used it would have to use the passive transport. the meaning of not using the active transport because if you use the active transport in one case it would burst
The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
Could an organism survive only by using passive transport never active transport?
There's an almost infinite number of organisms out there and I wouldn't be overly surprised if some could, but generally speaking, cells need active transport to maintain control over the substances entering and exiting. At the expense of some enrgy, active transport allows cells to control to some extent the molecules that are allowed to cross the plasma membrane. A basic example would be to say that in most human cells, waste products are secreted by active transport so without such a process there would be a toxic buildup in the cell; and also that glucose requires active transport to enter a cell so without it, the cell would have no form of energy and die
What organelles do cells need in order for active transport to occur?
Cells need organelles such as ATP-powered pumps, transport proteins, and vesicles for active transport to occur. These organelles help in moving molecules and ions across the cell membrane against their concentration gradient, requiring energy input. Active transport is essential for maintaining proper cellular function and homeostasis.
Large numbers of which organelle would be present in a cell that actively transports a lot of glucose across its membrane?
Active transport requires energy. Energy is released as a result of respiration, and respiration takes place in mitochondria. So major sites of active transport, such as kidney nephrons and villi in the small intestine need relatively large number of these organelles.
What a cell need to transport particles by active transport?
Energy
What transport may need to use energy to pass through cell membrane?
active transport
Does glucose need a transport protein?
Depends if it goes into the cell or out of the cell whether it is passive or active. Yes.
What are 2 situations which active transport would be required?
well if the active transport was not used it would have to use the passive transport. the meaning of not using the active transport because if you use the active transport in one case it would burst
How does diffusion from active transport?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
What is the different between active transport and passive transport of molecules across the cell membrane?
In an active transport, the cell uses energy (ATP) to transport the particle into the cell. Also, the particle moves through a "hallway" type thing. In a passive transport, the cell does not need energy (ATP) to transport the particle into the cell. Also, the particle just bursts through the cell membrane to get inside.
Under what two conditions would a cell need to use active transport?
When a molecule is too large to fit through the pores of the cell membrane....

How is facilitated transport different from active transport?
Facilated transport does not need to use energy but active transport does.
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
What role does active transport play in cell function?
Active transport is important for cell function as, various activities keep taking place such as manufacture of protein, fat, etc. For all these activities raw materials are needed which need to be transported to the various cell organelles. Also, the waste products too need to be transported out of the cell body.
What organelles do cells need in order for active transport to occur?
Cells need organelles such as ATP-powered pumps, transport proteins, and vesicles for active transport to occur. These organelles help in moving molecules and ions across the cell membrane against their concentration gradient, requiring energy input.
