6. All cells have lots of proteins and each performs a specific function based on its structure. All proteins are made by ribosomes. When we eat proteins, they are broken down to amino acids in our stomach and intestines and then delivered to each cell. each cell uses its ribosomes to synthesize the proteins it needs.

7. All cells have lots of proteins and each performs a specific function based on its structure. All proteins are made by ribosomes. When we eat proteins, they are broken down to amino acids in our stomach and intestines and then delivered to each cell. each cell uses its ribosomes to synthesize the proteins it needs. In our cells, there are two types of proteins that get made by the ribosomes: 1)Proteins that float around in the cytoplasm. for example: actin, tubulin and many more 2)Proteins that are secreted from the cell or bound to the membrane. for example: Insulin, LDL receptor, Aquaporin, and many more.

18. 1) All living things are composed of cells* 2) All cells come from pre-existing cells* * The Cell Theory 3) All cells exist in a water environment 4) All cells are bounded by a membrane 5) All cells have similar chemistrys (proteins, proteins, proteins) 6) DNA is the primary heritable molecule (DNA’s BIG job is to code for proteins) 7) The concept of gene regulation and totipotency
