What specific term refers a molecule that prevents extensive changes in pH?
The phosphate buffer system maintains the intracellular pH in all living organisms. In this buffer system, dihydrogen phosphate ions serve as the weak acid.
Is 10 NaCl isotonic hypertonic or hypotonic?
A 10 percent NaCl (sodium chloride) is hypertonic to red blood cells, as it is dependent on tonicity, which can be regarded as the relative concentration or osmotic pressure gradient of two semipermeable membrane separated solution.
What is the main function of ribosome?
Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).
Which organelle is responsible for protein synthesis?
Ribosomes. Ribosomes are the protein factories of the cell.
What is Cytoplasms?
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.
Which structure is the arrow pointing to what is the function of this organelle?
Answer: The arrow is pointing to the nucleus. The function of this organelle that it controls the activities of the cells.
Is 0.9 NaCl a hypertonic solution?
Hypertonic Solution If a cell with a NaCl concentration of 0.9% is placed in a solution of water with a 10% concentration of NaCl, the solution is said to be hypertonic.
What are examples of hypertonic solutions?
Common examples of hypertonic solutions are D5 in 0.9% normal saline and D5 in lactated ringers. The administration of hypertonic solutions should be monitored extremely closely, as they can quickly lead to fluid overload.
Is 0.45 NaCl a hypertonic solution?
Sodium Chloride 0.45% Solution for Infusion is a hypotonic solution, with an approximate osmolarity of 154 mOsm/l.
What is the Golgi apparatus function?
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.
What is the main function of Golgi apparatus Class 9?
Golgi Bodies Functions Its main function is the packaging and secretion of proteins. It receives proteins from Endoplasmic Reticulum. It packages it into membrane-bound vesicles, which are then transported to various destinations, such as lysosomes, plasma membrane or secretion.
What is the main function of ribosomes Class 9?
Functions of ribosomes: Ribosome provides space for the synthesis of proteins in the cell. Hence are called protein factories of the cell. Ribosome furnishes enzymes and factors needed for the formation of polypeptides.
