The molecule ___ is used to transfer energy from reactions which relase energy (such as cellular respiration) to processes that require energy (such as muscle contraction).
ATP
This biochemical pathway is used to release the chemical-bond energy of molecules such as carbohydrates to produce AtP. All organisms must be able to do this to survive
cellular respiration
Organisms such as green plants and algae capture solar energy and store the energy in the chemical bonds of carbohydrates. This process is called ___.
photosynthesis
The complete breakdown of glucose is also called ___ cellular repiration. It requires oxygen, and is more efficient than the process described in #5.
aerobic
If oxygen is not available, cells must use___ cellular respiration to produce the molecule described in #1. It does not require oxygen, but is less efficient than the process described in #4.
anaerobic
During aerobic cellular respiration, glucose is broken down to smaller molecules, releasing electrons and energy. This is an example of a(n) ___ reaction
oxidation
Which of these reactions is not a part of aerobic cellular respiration?
1. ethyl alcohol fermentation 2. glycolysis 3. electron transport system 4. Krebs cycle
ethyl alcohol fermentation
A biochemical pathway that starts with glucose and ends with pyruvic acid is:
glycolysis
Starting with pyruvic acid, which of these compounds can be produced by cellular respiration?
ethyl alcohol; lactic acid; carbon dioxide
Which of these compounds is produced by aerobic cellular respiration?
carbon dioxide
Which of these compounds is produced by anaerobic cellular respiration in human muscle tissue?
lactic acid
Which of the compounds is produced by anaerobic cellular respiration in yeast?
ethyl alcohol & carbon dioxide
How does the net gain of ATP for fermentation compare to the net gain of ATP for glycolysis alone?
fermentation produes the same amount of ATP as glycolysis
How does the net gain of ATP for fermentation compare to the net gain of ATP for aerobic cellular respiration?
fermentation produces less ATP than aerobic cellular respiration
