|---|---|---|---|---|---|
| 1.Enzymes | are substances that cause chemical reactions to occur faster.
🗑
|
||||
| 2.catalyst | enzymes are a type of catalyst
🗑
|
||||
| 3.substrates. | Ribosomes produce specific enzymes to act on specific substances,
🗑
|
||||
| 4.active sites. | Most enzymes have a surface with one or more deep folds. The folds make pockets
🗑
|
||||
| 5.enzyme’s shape | is key to how the enzyme functions.
🗑
|
||||
| 6.RNA polymerase is | enzymes that is essential to the process of transcription
🗑
|
||||
| 7.Molecules of mRNA are | transcribed by RNA polymerases and later new protein molecules are synthesized based on the instructions coded in the mRNA.
🗑
|
||||
| 8.Changes in temperature and pH can affect | the shape of an enzyme’s active sites
🗑
|
||||
| 9.enzymes are only able to | work properly in a certain temperature and pH range.
🗑
|
||||
| 10.the enzyme catalase assists in the | breakdown of hydrogen peroxide into water and oxygen
🗑
|
||||
| 11.Enzymes work by | decreasing the amount of energy needed to activate the chemical reaction.
🗑
|
||||
| 12.without enzymes catalyzing metabolic reactions | cells would not be able to perform metabolism quickly enough to support life13.
🗑
|
||||
| 13.Most enzymes are | proteins
🗑
|
||||
| 14.enzymes are produced by | a cell’s ribosomes.
🗑
|
||||
| 15.Ribosomes produce specific enzymes to | act on specific substances, called substrates
🗑
|
||||
| 16.the enzyme catalase assists in the breakdown of | hydrogen peroxide into water and oxygen.
🗑
|
||||
| 17.hydrogen peroxide is | catalyses substrate
🗑
|
||||
| 18.Enzymes are also important for | the synthesis of new molecules
🗑
|
||||
| 19.The shape of an enzyme determines | how it works
🗑
|
||||
| 20.Most enzymes have a surface with | one or more deep folds
🗑
|
||||
| 21.The active sites match folds in | the substrate’s surface
🗑
|
||||
| 22.Thus, a particular enzyme fits against | its substrate like two adjacent puzzle pieces
🗑
|
||||
| 23.protein are in what food | steaks
🗑
|
||||
| 24.proteins is a good source of nutrients | its good to eat. you shouldn't eat to much of it.
🗑
|

| 25.enzymes are a type of candy (-8 | no

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.
