A Tour of the Cell Overview: The Importance of Cells • All organisms are made of cells. o Many organisms are single-celled. o Even in multicellular organisms‚ the cell is the basic unit of structure and function. • The cell is the simplest collection of matter that can live. • All cells are related by their descent from earlier cells. Concept 2 Eukaryotic cells have internal membranes that compartmentalize their functions Prokaryotic and eukaryotic cells

Give an account of protein structure and function Protein structure 1 Proteins consist of amino acids joined together (in chains) 2 A protein is unique because of the sequence of amino acids 3 The amino acids are joined by strong peptide bonds 4 to produce the primary structure 5 Further (weak) hydrogen bonding between acids 6 produce the secondary and tertiary structures A maximum of 4 marks can be gained from this section.

Summary of The Cell Structure Bora Zivkovic introduces and describes the basic cell structure by using professional and academic language. First of all‚ she cites some comprehensible examples at the beginning of the article in order to explain that every cell has different size such as the largest animal cell - ostrich egg. She also emphasizes that it’s important to focus on the nuances. Then‚ she starts her main body. She introduces the basic structure of the cell from outer parts of the cell

protein from a cell. The steps involved in the synthesis‚ packing‚ and export of a protein from a cell are first‚ the ribosome makes a protein. Next‚ the proteins‚ gathered in the rough ER‚ are targeted for export to the Golgi apparatus in a vesicle. Finally‚ the Golgi apparatus modifies the protein that is than are shipped out of the cell. 4a. What is the function of mitochondria? The function of mitochondria is to convert chemical energy stored in food into compounds that are more convenient for

line. The boarding line moves items that are going to be boarded onto the plane. The Endoplasmic Reticulum does the same thing by moving items to different parts of the cell and serving as a pathway. Now we have the Golgi Apparatus which is kinda like the terminal. The Golgi Apparatus sends out finished products to the cell membrane‚ while the terminal is where passengers depart or arrive for their flight. Next comes the ribosomes‚ and their job is to assemble and build proteins. Their job is a lot

Prokaryotic cells are single celled organisms that were formed at the formation of the earth‚ so are the most basic life forms. The prokaryotes are organised in the ‘three domain system’ and include bacteria and blue-green algae. Prokaryotes live in many environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals. This is a diagram of a prokaryote cell and it shows that they are not very complex cells. They do not contain any membrane
