What is one way the cells in our bodies use lipids?
Cells use lipids as a source of energy, to form cell membranes, and to support the function of hormones and signaling molecules.
The function of a phagocyte is?
Phagocytes are very important components of our body's immunity (innate immunity). They are cells that can phagocytose foreign microbes (engulfing microbes by the cell membrane) and then they use enzymes to break down these foreign microbes. Phagocytes may also present the remnants of the microbe to a different type of cells (lymphocytes) to create a memory of that microbe in the body.
What is an organic compound called that is used to store energy and froms important parts of biological membranes?
Both lipids and sugars are impotent to membranes. Membranes are composed of phospholipids. They also contain glycoproteins, proteins that use sugars to help in communication between cells and identification.
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
What is an analogy for phagocytosis?
The phagocytes are the workers on the cleaning crew; they go around eating garbage, unwanted debris and the bad guys in town (phagocytosis). Each phagocyte also has a radio (chemical messenger) that they can use to call for more backup if they need it, like more phagocytes, killer-T cells, etc.
What are the survival techniques of jellyfish?
Jellyfish use stinging cells to protect themselves & catch food
What is one way that cells in our bodies use lipids?
Cells use lipids as a key component of cell membranes, providing structure and regulating what enters and exits the cell. Lipids also serve as a source of energy storage and insulation in the form of adipose tissue.
What do you now have to do to successfully use your cloned gene to transform mice?
To transform the mice, you can: 1. inject the gene into the cells with microscopically small needles 2. use electroporation (an electical pulse that creates temporary pores in the plasma membranes of the cells that DNA can go through) 3. use a powerful virus
Infer why endocytosis and exocytosis are important processes to cells?
because some molecules and partcles are too large to move by diffusion or to use the cell membranes transport proteins.
Is a fatty acid that is important for the structure and function of cell membranes?
Yes .,...... If you stop eating for any reason , the cells will take the fatty acid and try to use that like food
What is the use of sarkosyl in DNA isolation?
Sarkosyl is a detergent commonly used in DNA isolation to disrupt cell membranes and release DNA. It helps solubilize membrane proteins and lipids, allowing for the extraction of pure DNA from the cells. By disrupting cell membranes, sarkosyl helps in the efficient extraction of DNA from various sources.
How do protein pumps function within cells to regulate the movement of substances across cell membranes?
Protein pumps within cells use energy to move substances across cell membranes, regulating the flow of molecules in and out of the cell. These pumps can transport specific substances against their concentration gradient, maintaining the balance of ions and molecules inside and outside the cell.
