They involve in digestion.
They control all reactions of metabolism . Enzymes speed up all reactions in body .
Enzymes increase the rate of the chemical reactions carried out during metabolism.
The liver has a central role in lipid metabolism. The liver produces bile, which is required for efficient intestinal fat absorption. The post-absorptive stages of metabolism occur from the lipid absorption in the intestines.
It digests cell wastes, food molecules, and uses cell parts.
Lysosomes's role in metabolism is digestion.
Copper is a necessary co-factor for several enzymes. Most of them have to do with energy production.
Genes do play a role and have an effect on metabolism. For example if a persons family has many incidences of obesity, it is highly likely that person will also be obese because their genes will cause their metabolism to be slow.
if you are asking if that is true, not necessarily but metabolism does play a role in body fat amounts
Regulates metabolism and creates energy for food

the smooth endoplasmic reticulum has the role in cholesterol synthesis, fat metabolism, and detoxification of drugs
