In-s [12.5K]

Answer:

can cause large changes in enzymatic activity

Explanation:

An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.

An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.

When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.

Additionally, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.

Furthermore, an increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction.

In the human body, the optimal temperature for enzymes is around 37 degrees celsius (°C).

In conclusion, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.

Living things grow and develop.how are these two features of life different?
Akimi4 [234]
Basically, when something grows it demonstrates an increment in something you can check. A tree can grow. That implies that it adds to its tallness. We can number the inches it has developed. An association can develop, adding individuals or different gatherings to itself. These are numbered effortlessly. Benefit can grow, including cash in diverse ways. Growth without anyone else's input, in any case, can't gauge advancement. If we take a gander at the stature of a man, it might be anything but difficult to accept they are a grown-up. When I was in evaluation school, a comrade of mine was more than six feet when he was only 11 years of age. If we take a gander at how tall he was, he would be viewed as a grown-up. Be that as it may, at that age, my comrade wasn't sufficiently created in his reasoning, not to mention passionate growth, to be viewed as a grown-up. There is an enormous difference. Without a waste of time, what is development? Development envelops numerous things however it is demonstrated by the subjective change of circumstances. This implies that as something adds to the nature of the entire makes strides. As a tree creates, it won't just develop, additionally have the capacity to replicate, like a natural product, be sound and proceed with growing. Hopefully, this clears up the most evident contrasts between the term development and growth and can direct you to a few assets that will help you toward better comprehension!
