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)
