vocab 4 energy ATP enzymes

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Term
Definition
ACTIVATION   type of energy needed to start any chemical reaction  
🗑
ACTIVE SITE   the part of an enzyme that actually 'fits' the substance it works on  
🗑
CELLS   the smallest living parts of any living organism  
🗑
COENZYMES   organic molecules that can be used to change enzymes' shapes to make them work better  
🗑
DIFFUSION   the random movement of particles from higher to lower concentrations  
🗑
ENZYMES   molecules made of protein that are used to speed up chemical reactions in living cells  
🗑
EXERGONIC   chemical reactions that give off energy - an example would be a burning candle  
🗑
GLYCOLYSIS   energy needed to remake ATP from ADP comes from this process of breaking apart sugars  
🗑
HYDROLYSIS   process needs water to remove a phosphate from ATP in order to release energy  
🗑
KINETIC   also called the 'energy of motion', this is used by cells when they do work  
🗑
LYSOSOMES   organelles that break down food using powerful enzymes  
🗑
MULTICELLULAR   any organism that is composed of more than one cell is called this  
🗑
NITROGEN   element that is found in adenine, but not in ribose or phosphoric acid  
🗑
NUCLEUS   contains the genetic material (DNA) of a cell and controls all its functions  
🗑
PHOSPHORIC ACIDS   most of the stored energy in an ATP is found between these molecules  
🗑
POTENTIAL   type of energy that is stored in the high-energy bonds of ATP  
🗑
RIBOSE   the five-carbon sugar that is found in an ATP molecule  
🗑
RIBOSOMES   these organelles are necessary for producing the proteins that make up enzymes  
🗑
SUBSTRATE   the substance that an enzyme's shape attaches to (like a key fits in a lock)  
🗑
WATER   cytoplasm is made mostly of this; it's also given off during dehydration synthesis reactions  
🗑
ENDERGONIC   reactions that take in more energy than they give off - an example would be an cold pack you would put on a sprained ankle  
🗑


   

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.
