Answer 1

Lactic acid fermentation

This process is crucial for developing the flavor and texture of sourdough bread.

Question 2

What process occurs next to make the sourdough bread dough rise?

Answer 2

Alcoholic fermentation

This process creates pockets in the dough by forming ethyl alcohol and CO2 gas.

Question 3

What metabolic pathway begins glucose metabolism during intense exercise like the 100-meter sprint?

Answer 3

Glycolysis

This pathway is essential for producing quick energy.

Question 4

What takes over in the absence of oxygen during intense exercise?

Answer 4

Lactic acid fermentation

This process allows for continued energy production when oxygen is limited.

Question 5

What is a major global challenge driven by societal needs and wants?

Answer 5

Air and water pollution from industrial waste

This issue is critical for environmental health and sustainability.

Question 6

How do plants function in relation to pollution and energy production?

Answer 6

They act as small chemical factories

Plants synthesize carbohydrates through photosynthesis and utilize cellular respiration for energy.

Question 7

How can modern technology be applied to reduce industrial pollution?

Answer 7

Genetically modifying plants to synthesize compounds

This could replace hazardous waste-producing chemical factory processes.
