---|---|---|---|---|---|
mixture | a combination of substances in which the individual substances do not change or combine chemically but instead retain their own individual properties; can be gases, solids, liquids or any combination of them.
🗑
|
||||
organic compound | compounds that always contain hydrogen and carbon; carbohydrates, lipids, proteins, and nucleic acids are organic compounds found in living things
🗑
|
||||
enzyme | a type of protein that regulates nearly all chemical reactions in cells; a type of protein that speeds up chemical reactions in the body without being changed or used up itself
🗑
|
||||
inorganic compound | compound, such as H2O that is made from elements other than carbon and whose atoms usually can be arranged in only one structure
🗑
|
||||
passive transport | movement of substances through a cell membrane without the use of cellular energy; includes diffusion, osmosis, and facilitated diffusion
🗑
|
||||
diffusion | a type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them
🗑
|
||||
equilibrium | occurs when molecules of one substance are spread evenly throughout another substance
🗑
|
||||
osmosis | a type of passive transport that occurs when water diffuses through a cell membrane
🗑
|
||||
active transport | energy-requiring process in which transport proteins bind with particles and move them through a cell membrane
🗑
|
||||
endocytosis | process by which a cell takes in a substance by surrounding it with the cell membrane
🗑
|
||||
exocytosis | process by which vesicles release their contents outside the cell
🗑
|
||||
metabolism | the total of all chemical reactions in a organism
🗑
|
||||
photosynthesis | process by which plants and many other producers use light energy to produce a simple sugar from carbon dioxide and water and give off oxygen
🗑
|
||||
cellular respiration | process by which producers and consumers release stored energy from food molecules; series of chemical reactions used to release energy stored in food molecules
🗑
|
||||
fermentation | process by which oxygen-lacking cells and some one-celled organisms release small amounts of energy from glucose molecules and produce wastes such as alcohol, carbon dioxide and lactic acid
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
