pishuonlain [190]

Answer:

Golgi apparatus

Explanation:

Once the protein products are packaged in the endoplasmic reticulum into vesicles that fuse to the Golgi apparatus, these protein products are modified by enzymes. These changes are called post-translational modifications and include the addition of carbohydrates, lipids or some other functional groups. All these modifications are key for protein functionality. After this process is concluded, functional proteins are packaged into vesicles and released to their final destination inside or outside the cell.

Breaking chemical bonds is typically an endothermic process, which means energy must be added (it must pull in energy)

Breaking of chemical bonds is always endothermic meaning it wants energy, so it takes energy from its surroundings and sucks it in. Think of 'endo' as inside. The chemical bonds want energy inside of it so it can break.

Forming of chemical bonds is exothermic, meaning it releases energy into its surroundings. Think of 'exo' as outside, or exterior, it releases its energy outside of itself.

I hope that makes some kind of sense :)

This mutation is an example of a neutral mutation. Such mutations have no effect on an organism’s survival.
