Question

which process occurs when glucose is broken down by bacteria? this process is used in the production of cheese and yogurt. * 1 point
○ the krebs cycle
○ aerobic respiration
○ alcoholic fermentation
○ lactic acid fermentation

which process occurs when yeast cells break down glucose and release carbon dioxide? * 1 point
○ the krebs cycle
○ aerobic respiration
○ alcoholic fermentation
○ lactic acid fermentation

Explanation:

First Question:

To determine the process when glucose is broken down by bacteria for cheese and yogurt production, we analyze each option:

• The Krebs Cycle: Part of aerobic respiration, not specific to cheese/yogurt production.
• Aerobic Respiration: Requires oxygen, not the process for cheese/yogurt (which is anaerobic).
• Alcoholic Fermentation: Produces alcohol and CO₂, used in brewing/baking, not cheese/yogurt.
• Lactic Acid Fermentation: Bacteria convert glucose to lactic acid, used in cheese and yogurt production.

To find the process when yeast breaks down glucose and releases CO₂:

• The Krebs Cycle: Part of aerobic respiration, not the main process for yeast in this context.
• Aerobic Respiration: Requires oxygen, but yeast often uses fermentation in less oxygen.
• Alcoholic Fermentation: Yeast converts glucose to alcohol and CO₂ (e.g., in bread, brewing), matching the release of CO₂.
• Lactic Acid Fermentation: Yeast doesn't perform this; it's done by bacteria for lactic acid products.

Answer:

D. Lactic Acid Fermentation
