|---|---|---|---|---|---|
| Identify an enzyme from a list of compounds. | they usually end in ase.
🗑
|
||||
| What is the fate of pyruvic acid in an organism that uses aerobic respiration? | It is oxidized in the Krebs cycle.
🗑
|
||||
| What is a competitive | compete with the normal substrate for the active site of the enzyme.
🗑
|
||||
| What is a non competitive | acts on other parts of the apoenzyme or cofactor and decrease the ability to combine normal substrate
🗑
|
||||
| The sum of the chemical reactions in an organism | Metabolism
🗑
|
||||
| Provides energy and building blocks for anabolism. | CATABOLISM
🗑
|
||||
| Uses energy and building blocks to build large molecules | ANABOLISM
🗑
|
||||
| Substrate-Level Phosphorylation | high energy from an intermediate in catabolism is added to adp
🗑
|
||||
| Which of the following reactions produces the most molecules of ATP during aerobic metabolism? | Electron transport chain
🗑
|
||||
| processes generate ATP? | photophosphorylation
oxidative phosphorylation
substrate-level phosphorylation
🗑
|
||||
| What is the essential nutrient used by many bacteria in the synthesis of the coenzyme folic acid? | PABA
🗑
|
||||
| The enzyme-regulated energy-requiring reactions are involved mostly in | ANABOLISM
🗑
|
||||
| How many molecules of ATP can be generated from the three phases in the respiration of glucose? | 38
🗑
|
||||
| Apoenzymes are inactive by themselves and must be activated by | COFACTOR
🗑
|
||||
| In aerobic respiration, what is the fate of the pyruvic acid produced in glycolysis? | It is oxidized in the Krebs cycle.
🗑
|
||||
| The production of ATP driven by radient energy seen only in cells capable of photosynthesis. Light energy activates chlorophyll causing it to transfer an electron to an electron transport chain and, in the process, produce ATP from ADP and inorganic pho | Photophosphorylation
🗑
|
||||
| The energy released as carrier molecules are oxidized is used to generate ATP. | Oxidative Phosphorylation
🗑
|
||||
| Which of the following releases energy from sugars or other organic molecules by oxidation? | Fermentation
🗑
|
||||
| The energy from catabolic reactions is used to produce |
🗑
|
||||
| Where does the electron transport process occur in prokaryotic cells |
🗑
|
||||
| What is fermentation? | Any spoilage of food by microorganisms The oxidation of glucose with organic molecules serving as electron acceptors Any process that produces alcoholic beverages or acidic dairy products any large-scale microbial process occurring with or without air
🗑
|
||||
| What type of bacteria is most likely to go through fermentation? |
🗑
|
||||
| What are the end-products of lipid and protein catabolism |
🗑
|
||||
| Identify the role of ATP as an intermediate between catabolism and anabolism. |

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.
