There are structural and functional proteins present in cell. structural proteins such as myosin build up body. functional enzymes carry out biochemical reactions. Other proteins can be hormones, antibodies, cell surface molecules, ion channels, transporters, carriers etc.

Whats the function of ribosomes?

Ribosomes are responsible for protein synthesis in cells. They read the genetic information from messenger RNA (mRNA) and translate it into specific amino acids to build proteins. Ribosomes can be found in the cytoplasm of cells or attached to the endoplasmic reticulum.


Whats the function of Golgi complex?

The Golgi complex plays a role in packaging and sorting proteins and lipids into vesicles for transport to other parts of the cell or for secretion. It also modifies and processes these molecules before they are sent to their final destination within or outside of the cell.


Why don't proteins function properly unless they are immersed in water?

Proteins are dependent on water to maintain their three-dimensional structure, which is crucial for their proper function. Water molecules surround proteins and help to stabilize their structure by forming hydrogen bonds with the protein molecules. Without water, proteins may denature and lose their shape, leading to loss of function.


What is the most important function of proteins?

Proteins have many important functions in the body, but one of the most critical is their role in building and repairing tissues. Proteins are also essential for various biological processes such as enzyme activity, immune function, and cell signaling. Additionally, proteins play a crucial role in regulating gene expression and maintaining the body's overall structure and function.


What are the different kinds of proteins found in the human body and how do they function?

Proteins in the human body can be categorized into structural, enzymatic, regulatory, and transport proteins. Structural proteins provide support and shape to cells and tissues. Enzymatic proteins catalyze chemical reactions in the body. Regulatory proteins control various cellular processes. Transport proteins move molecules across cell membranes. Overall, proteins play crucial roles in maintaining the body's structure and function.
