Amino acids speed up or slow down the chemical reactions of organisms
Answer:
Golgi apparatus
Explanation:
The endomembrane system includes the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, several types of vacuoles, and the plasma membrane.
The Golgi apparatus consists of flattened membranous sacs called cisternae. They are stacked upon each other. The membrane of each cisterna in a stack maintains the unique internal space from the cytosol. Proteins and lipids formed on the ER are packed in many transport vesicles and are delivered to the Golgi apparatus.
The Golgi apparatus serves as a site for modification, and packaging of proteins and lipids. Modification of proteins in the Golgi apparatus results in the formation of several types of modified biomolecules such as glycoproteins. It serves as the site for the packaging of secreted proteins and sorting of other proteins to vacuoles and other organelles via transport vesicles. The transport vesicles carrying various biomolecules are formed in the trans face of the Golgi apparatus. These vesicles pinch off from the Golgi membrane and transport their contents to a specific destination.
Answer:
This is the famous extinction event that brought the age of the dinosaurs to an end. In each of these cases, the mass extinction created niches or openings in the Earth's ecosystems. Those niches allowed for new groups of organisms to thrive and diversify, which produced a range of new species.
