Resp Questions

These questions are to be answered as assigned. Do not lose this sheet.

1) Define respiration. __________________________________________________________

2) The common phrase that describes what happens during respiration is that you ________ your food

3) __________________________________ control respiration so that it can release energy a little at a time.

4) What cells or organisms don't respire? (sort of a trick question) ______________________

5) The two basic types of respiration are _____________________ and ____________________ The most obvious difference between them is that one uses ___________________ and the other doesn't.

6) Glycolysis is a process that breaks glucose down into ______________ acid and _______________ The hydrogen is stored on ________ Glycolysis releases enough energy for __________ATP

7) __________________________ is the process that combines the pyruvic acid and the hydrogen produced by glycolysis

8) One method of fermentation produces _______________ acid. This is used by certain ____________ that cause milk to _______________. This is also used by _____________ cells that are not getting enough _____________.

9) When lactic acid builds up in muscle cells, it causes a _________________ pain. Lactic acid also causes the pain of a ____________ attack when your heart muscles do not get enough _____________.

This happens when the ___________________ arteries become blocked.

10) Another method of fermentation produces ___________________ and __________________

This is used by ______________. We use yeast to make _________and __________.

11) The combination of glycolysis and fermentation is called __________________ respiration.

12) Either method of anaerobic respiration releases only enough energy for ________ATP.

13) The general equations for both examples of anaerobic respiration are:

______________ -----------> 2 _______________ + energy (___ATP)

______________ -----------> 2 _____________ + 2 ___________ + energy (____ATP)

14) Aerobic respiration is also called ______________________ respiration.

15) Cellular respiration starts with ___________________. This produces ______________ acid, some hydrogen (stored on ___________) and energy (___ATP)

16) The second step in cellular respiration is called the _______________ Cycle. In this cycle, pyruvic acid is broken down into ___________________ and _________________. The hydrogen is stored on either _________ or _________. What is released into the environment? ______________________

17) NAD is related to what vitamin? ___________ FAD is related to what vitamin? ________________

18) The Krebs cycle releases enough energy for _______ ATP.

19) The hydrogens that have been removed and stored on NAD or FAD have ________________ electrons.

20) The energy from these electrons is released as they pass from molecule to molecule along the ______________________________ chain.

21) The energy released is enough to form _______ATP.

22) At the end of the ETC, the hydrogens are combined with _______________ to form ___________

23) The Krebs Cycle and the ETC occur in the ________________________ of the cell.

24) The general equation for cellular respiration is:

_______________ + 6 _________ ---------> 6 _________ + 6 ________ + energy (___ATP)

25) What are the three parts to cellular respiration and for each one, how much ATP is produced?

a)__________________ - ______ATP b) ______________________ - _______ATP

c) __________________________ - _______ATP

26) Oxygen is needed in order to get rid of the ___________________ that were removed from the glucose.

27) In anaerobic respiration, hydrogens are not permanently removed and so no _________________ is needed. This, however, means that less ______________ is released.

28) Aerobic respiration produces more ATP than anaerobic because during aerobic respiration, ___________________ are removed and eventually combined with oxygen.

29) Fats have more calories than carbohydrates. This means that when you "burn" them, they release more _________________ Fats have more calories because their molecules contain more ______________ than carbohydrates.

30) Before amino acids can be "burned", what atoms must be removed from the molecules? ____________ What is this process called? _______________________ The nitrogen removed is eliminated as nitrogen waste in various forms. Give an example of nitrogen waste. ________________
