Engulfing, protein transfer, and ill get back to y'all on the last one lol

^^^

Those aren't really examples of active transport, just names of characteristics of an active transport.

Active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

Endocytosis-A process in which a cell takes in materials from the outside by engulfing and fusing them with its plasma membrane.

There are two types of endocytosis, called phagocytosis, which means cell-eating, and pinocytosis, which means cell-drinking.

Sodium-Potassium Pump-Nerve cell membranes also contain carrier proteins that actively transport sodium ions out of the cell and potassiu ions into the cell.

What is the process called when cells have to use energy to move materials through the cell membrane?

The process is called active transport. Active transport involves the movement of molecules across the cell membrane from an area of lower concentration to an area of higher concentration, which requires energy in the form of ATP.


Why do cells need to perform active transport?

Cells need active transport to regulate their internal environment. The ability of a cell to regulate its internal environment is important because it allows the cell to add substrates to reactions that are necessary for life. Primary active transport (the movement of molecules against their electrochemical gradient) helps to power secondary active transport (or co-transport) which is the transport of an ion/molecule against its electrochemical gradient, in company with an ion/molecule being transported with its electrochemical gradient.


Real life examples of endoplasmic reticulum?

Some real-life examples of the endoplasmic reticulum (ER) in action include the production of proteins in cells, such as insulin in pancreas cells, and the detoxification of drugs and toxins in liver cells. Additionally, the ER plays a crucial role in lipid metabolism in cells, which is important for membrane synthesis and energy storage.


What are real life examples of nuclear envelope?

The nuclear envelope is a double membrane structure that surrounds the nucleus of eukaryotic cells. One real-life example of the nuclear envelope is in human cells, where it helps to protect and segregate the genetic material within the nucleus from the rest of the cell. Another example is in plant cells, where the nuclear envelope plays a similar role in protecting and organizing the genetic material.


How is the way contrast functions in art similar to the way it functions in real life?

The way that light and dark create shadows is the same in both art and real life.
