Why is carbon important
nevsk [136]
Carbon is very important because Trees take it (Co2) in in order for oxygen to be produced.

All plants for the most part take in Co2 so that they can produce oxygen,
and we need that oxygen to live , to pump blood into our lungs so we can roam around.

It is basically one of the main components of our every day life on Earth.

I really hope this helps you a lot.

Which one of the following statements is true of enzyme catalysts? A) Their catalytic activity is independent of pH. B) They are
muminat

Answer:

D) They can increase the reaction rate for a given reaction by a thousand-fold or more.

Explanation:

Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
