Question
Answer
Oxidation and reduction reactions are chemical processes that result in a gain or loss in   electrons  
🗑
reactions that occur spontaneously and release free energy are called _ reactions   exergonic  
🗑
Protein catalysts that speed up the various metabolic biological reaction in an organism are called   enzymes  
🗑
Enzymes have specific _ with which they interact   substrates  
🗑
the chief energy currency of all cells is a molecule called   ATP  
🗑
Reactions that do not proceed spontaneously because they require energy from an outside source are called   endergonic  
🗑
enzymes catalyze chemical reactions by lowering the   activation energy  
🗑
RNA molecules that have been recently reported to act also as enzymes are given the name   ribozymes  
🗑
in an enzyme catalyzed reaction the reactant is called the   substrate  
🗑
at the conclusion of an enzyme catalyzed reaction, the enzyme   frees itself from the product and is ready to be reused  
🗑
ATP gives up energy when it is converted to   ADP and phosphate  
🗑
the temperature is raised slightly above the optimum for a specific enzyme. what would you expect to observe as a result of the change in temperature   decreased enzyme activity  
🗑


   

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.
