Some substances that help in active transport include ATP (adenosine triphosphate), which provides the energy needed for transport processes, and carrier proteins, which facilitate the movement of molecules or ions across the cell membrane against their concentration gradient. Sodium-potassium pumps are an example of a system that actively transports sodium and potassium ions across the cell membrane.
What else can I help you with?
Do all types of active transport use ATP energy?
Not all types of active transport directly use ATP as an energy source. Primary active transport relies on ATP to move substances against their concentration gradient, such as the sodium-potassium pump. In contrast, secondary active transport utilizes the energy generated from the movement of one molecule down its gradient to drive the transport of another molecule against its gradient, often indirectly linked to ATP usage. Therefore, while ATP is crucial in some active transport processes, it is not a requirement for all.
active transport reguires?
Active transport requires some form of energy input, usually ATP
What Lets things in and out of the cell wall?
The cell membrane regulates the passage of substances in and out of the cell. It does so through various mechanisms such as diffusion, facilitated diffusion, and active transport. Additionally, some substances may require specific channels or transport proteins to cross the membrane.
What is the energy needed for active transport s?
Active transport requires energy to move molecules against their concentration gradient, from areas of lower concentration to areas of higher concentration. This energy is typically derived from ATP (adenosine triphosphate) hydrolysis or, in some cases, from the energy stored in an electrochemical gradient. Active transport is crucial for maintaining cellular homeostasis and facilitating the uptake of essential nutrients, ions, and other substances.
What property in the cell membrane that allows only some substances in?
Semi-permeable. Permeable means things can pass through, so semi-permeable means only some things can pass through.
What function do protein perform in the cell membrane?
They help move material in and out of the cell.Read more:They help transport some substances through the membrane :)MORE: Membrane proteins are also important for endocytosis and cell signalling.

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

Why aren't osmosis and simple diffusion sufficient for the transport of all substances?
Osmosis and simple diffusion are not sufficient for the transport of all substances due to their nature. They only have the ability to transport substances which can pass through the cell membrane.

How does glucose concentration affect active transport?
Glucose concentration can affect active transport by influencing the rate of transport. In some cases, a higher glucose concentration can lead to an increased rate of active transport to maintain cellular homeostasis. Conversely, a lower glucose concentration may result in decreased active transport activity until a balance is restored.
Compare the contrast pasive and active cell transport process?
Passive transport is when materials move through the cell membrane without using energy. Active transport is when materials move through the cell membrane using the cell's energy. During Active transport a protein called ATP helps the material get through the cell membrane.
Is the transporting of molecules from the blood capillaries to body tissuse by active transport or bulk transport?
Neither except in the case of the sodium potassium pump. Transport of "molecules" is by osmotic pressure at the capillary bed and by and concentration gradient/ diffusion at the actual cell membranes.
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
