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.

The oceanic plate melts and forms magma and sinks back into the mantle. The magma can erupt through the continental plate like a volcano. so in other words it would be volcanoes
This process helps the necessary areas in the body to get the nutrients the blood carries. this is the curculatory system included with the other systems that creates a type of substance or nutrient the body needs.
Answer:
a state of sustained partial contraction
Explanation:
Simply said, muscle tone means that there is a sustained tension in a muscle wile in a determinate posture. The muscle tone enable us to mantaing our bodies in a posture fit for resting or for also working, like sitting, being stand up or in a couch or sleeping. The changes in the muscle tones make us able to move. So contractions will follow depending what activity we are engaged on, as a continous and passive partial contraction of muscles change following changes in direction.
Muscle tones have contractions that do not produce enough tension to move, buy they keep it tense and firm.
Thererefore the tension is balanced and resting muscle tone balances bones and joints.
See below :)
In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. It helps to maintain posture and declines during REM sleep.
