Some substances can go directly through the cell membrane, but other larger ones either go throuh channels or attach to a protein that aids them into the cell.

What is the process by which substances enter and leave cells and become distributed within cells?

Substances enter and leave cells through processes such as diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Once inside the cell, substances can become distributed within cells through diffusion, cytoplasmic streaming, vesicular transport, and interactions with organelles.


What do cells use to perform active transport?

Cells use energy in the form of adenosine triphosphate (ATP) to perform active transport. This energy is required to move substances against their concentration gradient, from areas of lower concentration to areas of higher concentration. Active transport allows cells to maintain internal conditions and regulate the movement of molecules.


Do paracellular or transcellular transport systems move substances across simple epithelia?

Paracellular transport systems move substances across simple epithelia by passing between adjacent cells through tight junctions, while transcellular transport systems move substances across simple epithelia by passing through the cytoplasm of the epithelial cells.


The internal transport of cells and dissolved substances is the function of?

The function of the internal transport of cells and dissolved substances is carried out by the circulatory system, which includes the heart, blood vessels, and blood. The heart pumps blood throughout the body, delivering nutrients, oxygen, and other substances to cells and tissues, while removing waste products for excretion.


Which part of plant cells prevents substances to go into and out of this cell?

The cell membrane is the part of plant cells that regulates the movement of substances into and out of the cell. It acts as a barrier, allowing only specific molecules to pass through via various transport processes such as diffusion, osmosis, and active transport.

When do cells do active transport?

When transporting substances from low to high concentration, or when transporting substances too large to pass through the membrane without assistance from a transport protein.


Why does active transport allow cells to accumulate substances in high concentrations where as passive means of transport do not?

Active transport uses energy from ATP to carry substances such as glucose to areas where it is required through the use of transport proteins. Whereas, facilitated diffusion is a passive process by which molecules move from an area of high concentration to an area of low concentration and it also depends on kinetic energy. Meaning that the distribution of molecules by facilitated diffusion will be random, whereas, active transport will have control over the direction of the concentration gradient.


What is the Bulk transport of substances out of the cell called?

Exocytosis is the process by which cells release substances by vesicle fusion with the plasma membrane, allowing bulk transport of molecules out of the cell.


What cells use to transport substance reproduce and perform chemical reactions?

Cells use various organelles such as vesicles, endoplasmic reticulum, and Golgi apparatus to transport substances within the cell. Additionally, cells replicate using the process of mitosis and carry out chemical reactions in specialized structures like the mitochondria and cytoplasm.

Why do cells need to use active transport?

Cells use active transport to move substances against their concentration gradient or across a membrane with the help of energy from ATP. This process is necessary for the cell to maintain proper internal conditions, such as ion balance and nutrient uptake, which are essential for its survival and functioning.


What substances used to help active transport occur within cells?

Proteins are major substances involved in active transport within cells. Examples include ion pumps like Na+/K+ ATPase and transporters like glucose transporters. ATP provides the energy needed for these proteins to actively transport molecules across the cell membrane.
