The term criminal record refers to the formal record of offences that you have been convicted of in a court. This means that only offences that you have pleaded guilty to or been found guilty of after trial, will show up in your criminal record.
However, Rubisco is not very efficient at grabbing CO 2 , and it has an even worse problem. When the concentration of CO 2 in the air inside the leaf falls too low, Rubisco starts grabbing oxygen instead. The ultimate result of this process, called photorespiration, is that sugar is burned up instead of being created.
For example, the enzyme family of matrix metalloproteinases (MMP) is known to mediate the oxidative effect of UV light on human skin in vivo. The consequences of elevated MMP expression are reduced dermal collagen synthesis and connective tissue damage, corresponding to the macroscopic appearance of photodamaged skin. It has been shown that MMP expression is increased in endogenously aged but photoprotected skin, resulting in impaired collagen synthesis. Moreover, topical vitamin A and its analogues inhibit the expression of MMP and stimulate collagen synthesis in both photodamaged and photoprotected aged skin.
