What is the thin structure that surrounds a cell known as?
The thin structure that surrounds a cell is known as the cell membrane, or plasma membrane. It acts as a protective barrier, controlling the passage of substances in and out of the cell, and plays a key role in maintaining the cell's internal environment.
What cell organelles lack membranes as part of their structure?
Ribosomes and centrioles are cell organelles that lack membranes as part of their structure. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
Which type of blood cell has a major role in immunity to infectious disease?
White blood cell (WBC) has a major role. It fights with the germs of infections in the body.
What is the major component of a typical animal cell determines structure and function?
The cell membrane is a major component of an animal cell that determines its structure and function. It acts as a protective barrier, regulates the passage of substances in and out of the cell, and plays a key role in cell communication and signaling.
Does cell structure determine functions?
Yes, cell structure plays a crucial role in determining the functions of a cell. The specific organelles present and their arrangement within a cell influence its ability to carry out specific tasks such as energy production, protein synthesis, or waste removal. Variations in cell structure contribute to the diverse functions of different cell types in the body.
What role do sigma factors play in gene regulation and transcriptional initiation?
Sigma factors are proteins that help RNA polymerase bind to specific DNA sequences, allowing for the initiation of transcription. They play a crucial role in gene regulation by determining which genes are transcribed and when, thus controlling the expression of various proteins in the cell.
What makes proteins in a cell structure?
Proteins in a cell provide structure by forming filaments and networks that help maintain cell shape and integrity. They also contribute to the structure of organelles within the cell, such as the cytoskeleton and cell membrane. Additionally, proteins play a role in cell adhesion and cell-to-cell communication, which are essential for maintaining tissue structure and function.
What role does cholesterol play in the membrane structure and function?
Cholesterol is a type of lipid that helps maintain the fluidity and stability of cell membranes. It helps regulate the movement of molecules in and out of the cell, and also plays a role in signaling pathways within the cell. Overall, cholesterol is important for the structure and function of cell membranes.
What is the thin structure that surrounds a cell known as?
The thin structure that surrounds a cell is known as the cell membrane, or plasma membrane. It acts as a protective barrier, controlling the passage of substances in and out of the cell, and plays a key role in maintaining the cell's internal environment.
What cell organelles lack membranes as part of their structure?
Ribosomes and centrioles are cell organelles that lack membranes as part of their structure. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
Supporting structure of the cell that is involved in movement?
In cells (Bacterial), the structure present for movement is Flagella.In human cells, no such structure is present, then also movement occurs.There is a molecular mechanism attached with it.The presence of calcium ions (intracellular) which on excitation binds with the specific protein and initiate the chain of reaction which leads to contraction. It produces movement.Ca-Calmodulin complex-Initiation of Myosin light chain kinase-Phosphorylation-Contraction.
Which type of blood cell has a major role in immunity to infectious disease?
White blood cell (WBC) has a major role. It fights with the germs of infections in the body.
The function of a cell depends primarily on?
structureThe shape of the protein will determine the cell. It will also determine the function of the cell.
What role does cholesterol play in the cell membrane?
Cholesterol helps maintain the structure and fluidity of the cell membrane by preventing it from becoming too rigid or too fluid. It also plays a role in regulating the movement of molecules in and out of the cell.
What is the major component of a typical animal cell determines structure and function?
The cell membrane is a major component of an animal cell that determines its structure and function. It acts as a protective barrier, regulates the passage of substances in and out of the cell, and plays a key role in cell communication and signaling.
What is a cell structure?
A cell structure refers to the different components within a cell that help it carry out its functions. These structures can include the cell membrane, nucleus, cytoplasm, mitochondria, and other organelles. Each structure plays a specific role in maintaining the cell's health and supporting its various functions.
What is stored in the vacuole of a cell?
The vacuole of a cell stores water, nutrients, and waste products. It helps maintain the cell's shape and structure, and plays a role in regulating the cell's internal environment.
