Question
Answer
Aerobic respiration   process that produces large amounts of ATP  
🗑
2 stages of Aerobic respiration   Krebs cycle and Electron Transport Chain  
🗑
Krebs Cycle   First stage of Aerobic Respiration; It is a biochemical pathway that breaks down acetyl CoA  
🗑
Products of Krebs cycle   co2, H atoms, and ATP  
🗑
How many ATP molecules are made in CR?   maximum ATP made=38  
🗑
Glycolysis   pathway in which two molecules of pyruvic acid are produced  
🗑
When cells break down food molecules, energy   is temporarily stored in ATP molecules  
🗑
ATP   is essential for a cell to perform all the tasks necessary for life  
🗑
a substance produced during photosynthesis that is used for completion of cellular respiration is   oxygen  
🗑
when glycolysis occurs,   a molecule of glucose is split, two molecules of pyruvic acid are made, and some ATP is produced  
🗑
the name of the process that takes place when organic compounds are broken down in the absence of oxygen   fermentation  
🗑
When muscles are exercised extensively in the absence of sufficient oxygen,   lactic acid is produced  
🗑
pyruvic acid   three-carbon product of glycolysis  
🗑
NADH is a/an   an electron carrier  
🗑
Anaerobic means   without oxygen  
🗑
alcoholic fermentation...   makes ethyl alcohol  
🗑
kilocalorie   unit of energy  
🗑
cytosol   location of glycolysis  
🗑
NAD+   electron acceptor  
🗑
cell membrane   location of electron transport chain in prokaryotes  
🗑
yeast cells produce alcohol and carbon dioxide in the process of   alcoholic fermentation  
🗑
in cellular respiration, glycolysis immediately precedes the   krebs cycle  
🗑
in CR, more energy is transferred in..   the electron transport chain, than in any other step  
🗑
The breakdown of organic compounds to produce ATP is known as   cellular respiration  
🗑
An important molecule generated by both lactic acid fermentation and alcoholic fermentation is   NAD+  
🗑
The energy efficiency of CR is approximately   39 percent  
🗑
The krebs cycle occurs in the   Matrix  
🗑
mitochondrial matrix   the space inside the inner membrane of a mitochondrion  
🗑
citric acid   six-carbon molecule in the Krebs cycle  
🗑
NAD+   electron carrier molecule that is oxidized when G3P is reduced  
🗑
FAD   electron carrier molecule similar to NAD+  
🗑
oxaloacetic acid   four-carbon molecule that combines with acetyl CoA  
🗑


   

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.
