Proteins can have functions such as enzyme activity, structural support, signaling, transport, and defense. Other molecules like lipids can serve as energy storage, cell membrane components, and signaling molecules. Carbohydrates can function as a source of energy or as structural components in cells.

In addition to proteins organic molecules is also found in cellular membranes?

Three different types of molecules appear in the membrane of a cell. These molecules are lipids, proteins, and carbohydrates.


What are the some complex food molecules?

Starch (polysaccharide), proteins, and lipids are some complex food molecules.


What are the four most abundant elements in the human body What are some of the molecules they help form and why are these molecules important in terms of their biological functions?

The first four elements are oxygen, carbon, hydrogen and nitrogen.They form water, proteins, enzymes, etc.


What does a cell membrane have that makes it easier for certain molecules to cross the cell membrane?

Cell membranes have proteins like channel proteins and carrier proteins that facilitate the transport of certain molecules across the membrane. These proteins provide specific pathways for molecules to pass through, making it easier for them to cross the membrane. Additionally, some molecules can cross the membrane through simple diffusion if they are small and non-polar.


Do all integral proteins move quickly?

No. The movement of integral proteins cannot be generalized. Integral proteins are those that are embedded into the cell membrane. A part of the protein might be a receptor outside the cell while the other end might extend into the cytoplasm. However, their movement depends on their function. Some integral proteins may not move and remain static whereas other may move to a different location in search of molecules called second messengers

Why do cell need transport proteins to functions?

Some molecules are too large to pass through the cell membrane without transport proteins.


What are some examples of complex molecules found in nature?

What are the different types of protein motifs and how do they contribute to the structure and function of proteins?

Protein motifs are recurring patterns in protein structures that play important roles in their function. Some common types of protein motifs include alpha helices, beta sheets, and turns. These motifs contribute to the overall structure of proteins by providing stability and facilitating interactions with other molecules. They also help determine the specific functions of proteins by influencing their shape and ability to bind to other molecules.

Does all DNA code for proteins?

No, not all DNA codes for proteins. Some DNA codes for other molecules like RNA or regulatory elements that control gene expression.

Do all genes code for proteins?

No, not all genes code for proteins. Some genes code for other types of molecules, such as RNA, which play important roles in regulating gene expression and other cellular processes.

Functions of proteins embedded in the membrane?

There are two types of proteins that are embedded in phospholipid membranes, extrinsic and intrinsic. Extrinsic proteins are only partially embedded in the membrane. They aid the structural stability of the membrane and when in conjunction with glycolipids can be involved in cell recognition. Intrinsic proteins pass all the way through a membrane. Some of them may be channel proteins which act as passages through the membrane for some molecules and ions.


The major functions of lipids in a organism do not include?

The major functions of lipids in an organism do not include providing structural support (like proteins do) or directly aiding in enzyme catalysis (like proteins and some vitamins do). Lipids primarily act as energy storage molecules, form cell membranes, and help with insulation and protection of organs.
