Molecules & Movement

This reviews the vocab found in Unit 1 - Molecules & their Movement

QuestionAnswer
organic compounds are CHains of repeating molecules that contain all three elements Carbon, Hydrogen and Oxygen.
Protein an organic compound made of a chain of amino acids. This type compound controls chemical reactions, fighting foreign invaders, sending messages, pigments, structure and more.
Carbohydrate an organic compound made of a chain of glucose/simple sugar molecules. It gives the cell quick energy.
Lipid an organic molecule that is made of a chain of fatty acid/glycerol molecules. It helps with stored energy, creates waxes and provides warmth/protection.
Nucleic Acid an organic compound made of nucleotides. This compound stores hereditary information (DNA/RNA) that is used to make proteins.
Glucose a simple sugar that chains together to form a carbohydrate and a more complex starch. An ingredient for our cells to make energy.
Amino Acids these chain together in a very specific order to create a protein.
Nucleotide these chain together to create a nucleic acid containing a code for the production of proteins
Starch a complex arrangement of glucose molecules
Starch indicator when placed in the presence of starch, this indicates that starch is present by changing colors to blue/black.
Glucose indicator when placed in the presence of glucose and heated, this indicates that glucose is present by changing colors to bright orange.
Enzyme/Biological Catalyst this is a type of protein that speeds up chemical reactions (digestion and synthesis). They are specific to one reaction.
Transport this is the movement of materials in and out of a cell membrane and throughout the organisms .
Diffusion this is the movement of molecules into and out of cells from an area of higher concentration to an area of lower concentration without using energy.
Osmosis diffusion of Water.
Active Transport the movement of molecules against diffusion from low concentration to high concentration. This TAKES ENERGY.
