Cellular respiration uses oxygen to convert the chemical energy stored in organic molecules into
a phosphate group is removed
Energy is releasd from ATP when
glycolysis--->Krebs Cycle-->electron transport chain
Which of the following is the correct sequence of events in cellular respiration?
alcoholic fermentation
Which process is used to make bread rise?
Photosynthesis uses carbon dioxide, and cellular respiration produces it
How are cellular respiration and photosynthesis almost oppocite processes?
Which of the following is NOT a part of an ATP molecule? Adenine, Ribose, Chlorophyll, Phosphate
used ATP is discarded by the cell as waste
Which of the following is NOT a true statement about ATP? ATP consists of ribose, adenine, and phosphate; ADP forms when ATP releases energy; ATP provides energy for cells; used ATP is discarded by the cell as waste
Which of the following is released during cellular respiration? Oxygen, air, energy, lactic acid.
glucose and oxygen
What are the reactants in the equation for cellular respiration?
Cellular respiration is called an aerobic process because it requires
Which of these processes takes place in the cytoplasm of a cell? glycolysis, electron transport, Krebs Cycle, all of the above
lactic acid fermentation
One cause of muscle soreness and fatigue is
True/False: (Photosynthesis) uses the sun's energy to convert water and carbon dioxide into sugars
True/False: The products of (glycolysis) are 2 ATP, 2 NADPH, and 2 pyruvic acid molecules.
ATP synthase
True/False: Protein structures in mitochondria that act like miniature turbines and convert ADP into ATP are called (electron transport chains)
True/False: Unlike cellular respiration can be used to release energy even in the absence of (carbohydrates).
True/False: Cellular respiration uses (carbon dioxide) to convert the chemical energy in organic molecules into ATP.
True/False: The reactants of photosynthesis are the same as the (reactants) of cellular respiration.
True/False: The Krebs cycle produces electron carrier molecules that are important in the (electron transport chain).
