<span>The finding this indicates is most likely peritonitis. Rebound tenderness refers to pain felt when pressure is removed instead of applied, such as taking your hand away from holding a wound or perceived injury such as chest pain. In this situation there is usually an infection and it can be quite deadly. The pain is caused by seepage or a tear somewhere in the intestines.</span>
Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
Hello there :)
I am quite sure this is a true/false question
This statement is false.
Yes, the cilia and mucus in the trachea does sweep upward, however, it moves the mucus towards the pharynx where it is swallowed not towards the nose where it is sneezed out.
The decline in bone breakdown and increased mineralization causes blood calcium to decrease <span>back to normal levels. This happens when there is secretion of calcitonin. This circulation calcitonin is inhibiting </span>osteoclasts<span> and it will stimulate osteoblasts within minutes. The effect of this on osteoclast will cause a decrease in reabsorption and a concurrent increase in deposition because of the osteoblasts activity.</span>
