Embedded in the semi-permeable cell membrane are many different types of carrier proteins or channel proteins. These globular proteins allow the transport of specific substances from the outside of the cell into the cell or vice versa.
Specific means each protein can only transport one type of substance across. For example, Protein A can transport Substance X but not Substance Y. Substance Y has to be transported by Protein B which cannot transport Substance X. The specific nature of these globular proteins mean it is easier for these molecules to be transported.
What else can I help you with?
What function does the membrane perform in an animal cell.?
helps control transport of material into and out of the cell
What kinds of proteins can be found in cell membranes?
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
To perform active transport cells use?
In active transport, cells use energy (usually from ATP) to move molecules against their concentration gradient across a cell membrane. This process allows cells to accumulate molecules or ions inside the cell or expel them outside, maintaining the cell's internal environment and enabling various cellular functions. Examples of active transport mechanisms include the sodium-potassium pump and the hydrogen-potassium pump.
What are the functions that cell membranes perform?
Cell membranes perform several key functions, including acting as a barrier to regulate the passage of substances in and out of the cell, providing structural support to the cell, facilitating cell communication and signaling, and recognizing and binding to specific molecules like hormones or antigens.
What function does the membrane perform in an animal?
helps control transport of material into and out of the cell
What function does the membrane perform in an animal cell.?

What is the key factor that enables objects to perform work?
The key factor that enables objects to perform work is energy.
Two roles of membrane proteins?
Some membrane proteins are receptors for hormones or other chemicals. Some membrane proteins perform active transport of substances into or out of the cell.
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.
What organelle has membrane bound structures inside a cell that perform specialized functions?
The organelle that has membrane-bound structures inside a cell that perform specialized functions is the endoplasmic reticulum. The endoplasmic reticulum plays a key role in the synthesis, folding, and transport of proteins and lipids within the cell.
What functions do carrier proteins perform in active transport?
Carrier proteins in active transport actively pump molecules or ions against their concentration gradient across a cell membrane using energy from ATP. They allow specific substances to be moved across the membrane in a controlled manner, helping to maintain cellular homeostasis and regulate cell function.
What enables you to perform specific computer tasks?
system
What enables animals to perform different functions?
The organ that enables animals to perform different functions is the cell. The cell is regarded as the basic unit of all living organisms.
Where does a Electron Transport Chain happen?
In aerobic respiration, electron transport occurs inside the mitochondria. In photosynthesis, electron transport occurs inside the chloroplasts.
Which hormone enables a person to perform feats of strength?
adrenaline
What are the two main groups in a plasma membrane of organic molecules?
The two main groups in a plasma membrane of organic molecules are lipids and proteins. Lipids, such as phospholipids, form the structure of the membrane, while proteins are embedded within the lipid bilayer and perform various functions such as transport, signaling, and cell adhesion.
