Proteins serve a myriad of functions in the body, including structural support (e.g., collagen in connective tissues), transport (e.g., hemoglobin transporting oxygen in blood), enzymatic activity (e.g., lactase facilitating lactose digestion), and immune response (e.g., antibodies targeting pathogens). Additionally, proteins like hormones (e.g., insulin regulating blood sugar) play crucial roles in signaling and communication within and between cells. Each protein's specific function is determined by its unique sequence of amino acids and three-dimensional structure.
What else can I help you with?
Are transparent proteins responsible for secreting proteins?
Transport proteins are not responsible for the secretion. Golgi vesicles transport proteins. Proteins synthesis occur in cytoplasm.
What organelle is responsible for actually making proteins?
The organelle responsible for making proteins is the ribosome. Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum, where they synthesize proteins by translating messenger RNA (mRNA) sequences into polypeptide chains. This process is essential for cell function, growth, and repair.
What is the function of the nucleus in a neuron?
The nucleus in a neuron contains the cell's genetic material and controls the cell's activities by regulating gene expression. It is responsible for producing the proteins necessary for the neuron's structure and function.
What is the function of the DNA molecule?
The function of DNA is to store genetic information that codes for the synthesis of proteins in living organisms. It serves as the blueprint for an organism's development, growth, and function. DNA is passed from parents to offspring and is responsible for the heredity of traits.
Which cell is responsible for controlling cell function?
The nucleus is responsible for controlling cell function. It contains the cell's DNA, which holds the instructions for making proteins and determining the cell's characteristics. The nucleus regulates protein synthesis and coordinates the cell's activities.

What is function of proteins?
There are many functions of proteins. They are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues. The human body is about one half muscle, and muscles are mostly made of proteins. There are seven main types of protein: antibodies, contractile proteins, enzymes, hormonal proteins, storage proteins, structural proteins, and transport proteins.
Function of a rough endoplasmic reticulum?
They have ribosomes that finish translating proteins that will either be embedded into the membrane or be exocytosed out of the cell. They are responsible for finishing translation and handing the proteins off to the Golgi for further modification.
Is responsible for assembling proteins in the cell.?
Ribosomes are responsible for assembling proteins in the cell by reading mRNA transcripts and facilitating the process of translation to produce the protein structures. Ribosomes are composed of proteins and RNA molecules and can be found in the cytoplasm or on the endoplasmic reticulum in eukaryotic cells.
What do ribosomes make for cell activities?
Ribosomes are responsible for synthesizing proteins by translating the genetic information from mRNA. Proteins are essential for various cell activities, including cell structure, function, and regulation.
What percent of DNA is responsible for coding proteins?
Approximately 1-2 of DNA is responsible for coding proteins.
What is the function of the DNA molecule?
The function of DNA is to store genetic information that codes for the synthesis of proteins in living organisms. It serves as the blueprint for an organism's development, growth, and function. DNA is passed from parents to offspring and is responsible for the heredity of traits.

The nucleus is responsible for controlling cell function. It contains the cell's DNA, which holds the instructions for making proteins and determining the cell's characteristics. The nucleus regulates protein synthesis and coordinates the cell's activities.
What are the function if proteins?
Proteins are made of amino acids.
What is the function of Endoplasmic in animal cells?
There are two types of endoplasmic reticulum in an animal cell. The rough endoplasmic reticulum is responsible for making proteins. The smooth endoplasmic reticulum is responsible for synthesizing steroids, phospholipids, and lipids.
What is responsible for the assembling of proteins?
RNA assembles amino acids into proteins.
