Poisons and medicines with enzymes Flashcards
What does cyanide do to the body?
It is potassium cyanide (KCN) and inhibits aerobic respiration and catalase
It makes hydrogen cyanide in the body which can easily dissociate into H+ and CN- ions,
CN- binds irreversibly to an enzyme in mitochondria inhibiting the reaction
What does snake venom do to the body?
It inhibits the enzyme AChE which is used at neuromuscular synapses so the ACh stays at the receptors of the muscle membrane so the muscles is contracted
This causes paralysis in a person
What does aspirin do to the body?
It binds to enzymes that catalyse prostaglandin formation, which help in signalling other molecules of an infection. Damaging this cause nerve cells to be less senses to pain and can reduce the risk of blood clots and strokes
Who is aspirin bad for?
Under 12 year olds because it can damage their stomach lining
What do ATPase inhibitors do to the body?
They treat heart failed and atrial arrhythmia
They inhibit the sodium potassium pump in the cell membranes of the heart muscle cells so more calcium enters the cells to increase muscle contractions which strengthens the heart best
What do ACE inhibitors do to the body?
These lower your blood pressure and to treat heart failure
What do protease inhibitors do to the Cody
They prevent the replication of of the virus
