7. Describe the functions of lysosomes

Answer 1

1)The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell. The Golgi apparatus is sometimes compared to a post office inside the cell since one major function is to modify, sort, and package proteins to be secreted.

2)Two main type of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)

3)A hypotonic solution is a solutionwhere the concentration of solute is low, which translate to a high water concentration. Hence, if a red blood cell is placed in a hypotonic solution, water would naturally enter the cell through osmosis as the concentration of water in the RBC is lower.

4)Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP. ... Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy.

5)Ribosomes are called the protein factory of the cells. ... Ribosome because it gathers simple amino acids and make it as long peptide chain or protein.

6)ATP stands for adeinosine triphosphate. ... ATP is called the energy currency of the cell, and of life, because it is the energymolecule that all cells need in order to do anything within the human body. The molecule is used like a battery within cellsand allows the consumption of one of its phosphorous molecules.

7)Inside a cell, numerous organelles functionto remove wastes. One of the key organelles involved in digestion and waste removal is the lysosome. Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
