Chapter 6

Question 1

Explain how the processes of photosynthesis and cellular respiration are complementary to each other.

Answer 1

Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances. They both consume and create the same substances (water, glucose, oxygen, and carbon dioxide) but in different ways.

Question 2

equation for cellular respiration

Answer 2

C6 H12 O6 + 6O2 –> 6CO2+ 6H20+ ATP

Question 3

Compare and Contrast Anaerobic vs. aerobic metabolism and be able to relate to athletes.

Answer 3

both start with gycolosis and produce ATP but anaerobic produces very little. athletes tire sooner with anaerobic exercise and it produces more lactic acid which produce soreness.

Question 4

When does fermentation occur?

Answer 4

Fermentation occurs if there is not enough oxygen for aerobic respiration. The type of fermentation depends on the kind of cell, since some cells. like yeast, carry out alcoholic fermentation; some cells like, vertebrate muscle cells, carry out lactic acid fermentation.

Question 5

What are two types of fermentation?

Answer 5

alcoholic fermentation and lactic acid fermentation

Question 6

What is produced in each type of fermentation?

Answer 6

Alcoholic fermentation is the process by which certain cells convert pyruvate (a product of glycolysis) into ethyl alcohol and carbon dioxide. Yeast in bread carries out this process, and the CO2 causes the bread to rise. During lactic acid fermentation, pyruvate is used to form lactic acid

Question 7

What is the energy yield of fermentation?

Answer 7

2 ATP

Question 8

what is the significance of the fermentation process?

Answer 8

?

Question 9

how do we make use of fermentation?

Answer 9

picketing, alcohol, turning bacteria into milk and bread, yeast causing bread to rise.
