Chapter 8 biology
How many ATP molecules ar produced per molecule of glucose during glycolysis
2 ATP
What is the end result of cellular respiration in humans?
ATP + H2O
How does cellular respiration release energy?
By breaking down food molecules
Write the chemical and word equation for cellular respiration.
C6 H12 O6 + 6 O2 --> 6 CO2 + 6 H2 O + 46 ATP Glucose + oxygen --> carbon dioxide + water + ATP
What gas do organisms give off during cellular respiration?
Carbon dioxide
How is energy for use in cells stored?
Chemical bond energy (ATP)
Where does the synthesis of glucose take place in a plant cell?
Choroplasts
What process creates air bubbles in bread and gives it a spongey texture?
Fermentation
Write the chemical and word equation for photosynthesis.
H2O + CO2 + sunlight --> O2 + C6H12O6 Carbone dioxide + water + sunlight --> glucose (sugar) + oxygen
photosynthesis
Light energy is stored as chemical energy in organic molecules. Carbon dioxide + water + sunlight --> glucose + oxygen
If a large amount of trees where cut down nationwide, what impact might that have on our carbon dioxide and oxygen in the air?
More carbon dioxide and less oxygen in the air.
What gas do plants give off during photosynthesis?
Oxygen
Explain why aerobic respiration is considered more efficient than anaerbobic respiration
Produces more ATP
Explain how photosythesis and cellular respiration are similar and how they are different.
These processes use the same molecules but are the reverse of each other. The products of photosynthesis are the reactants of cellular respiration. Be able to give the equations.
cellular respiration
breakdown of glucose (C6 H12 O6) in the presence of the oxygen (O2) to produce cellular energy (ATP)
