Pneumococcal pneumonia is a type of pneumonia that is caused by the bacterium Streptococcus pneumoniae. It's a very common infection and can be fatal if left untreated.
The symptoms of this pneumonia include chills, fever, coughing (that may include rusty or blood-streaked sputum), shortness of breath, chest pain, rapid breathing, vomiting, nausea, loss of appetite and headaches.
If it cannot avoid it, it just find a mechanism to use oxygen and make it less harmful to itself. This is how the process of cellular respiration may have evolved
Answer:
Ligand-receptor interaction is the first interaction that triggers cell signalling.
Ligands are the hormones, drugs or neurotransmitters that specifically bind with receptors present in cell surface to initiate cell signalling. Ligand binding to the receptor is reversible. Binding of the ligand to the receptor can activate or inactivate receptor. Activation may lead to cell signalling pathways. Inside cells, there are secondary molecules which on activation starts a cascade of reactions. which in-turn regulate the function of the ligand molecule.
At first, the activated receptor relates with G proteins molecules in the cell.
before the ultimate physiological effect of the ligand on the cell's behavior is produced Therefore, the cellular signaling starts as soon as the first messenger (the ligand) binds to its receptor.
hope this helps
