QUIZIZZ CHAPTER 7.3 (F4): FERMENTATION

What is fermentation?

• Complete breakdown of glucose with oxygen

• Incomplete breakdown of glucose without oxygen

• Complete breakdown of glucose without oxygen

• Incomplete breakdown of glucose with oxygen

How is fermentation different from aerobic respiration?

• It occurs in the presence of oxygen

• It breaks down pyruvate incompletely after glycolysis

• It produces more energy than aerobic respiration

• It does not involve glycolysis

What happens to pyruvate after glycolysis in fermentation?

• It is converted into water

• It undergoes either alcohol or lactic acid fermentation

• It is used in aerobic respiration

• It is stored as fat

What is fermentation?

• The complete breakdown of glucose in the presence of oxygen.

• The incomplete breakdown of glucose in conditions of limited oxygen or without oxygen.

• The process of photosynthesis in plants.

• The conversion of water into oxygen and hydrogen.

What is the main product of alcohol fermentation from glucose?

• Ethanol

• Water

• Oxygen

• Lactic acid

What gas is released by yeast that causes bread dough to rise?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

What ability do paddy plants have that allows them to survive in waterlogged areas with less oxygen?

• They can carry out alcohol fermentation.

• They can photosynthesize without sunlight.

• They can absorb more water than other plants.

• They can grow in dry soil.

What enzyme do paddy plants produce to break down ethanol molecules?

• Alcohol dehydrogenase enzymes

• Photosynthesis enzymes

• Protein synthesis enzymes

• Respiration enzymes

What is the process called where glucose is broken down into lactic acid and energy?

• Photosynthesis

• Lactic Acid Fermentation

• Cellular Respiration

• Alcoholic Fermentation

What role does Lactobacillus play in the production of yoghurt based on fermentation?

• It adds lactic acids to coagulate the milk and taste sour

• It adds sweetness to the yoghurt.

• It makes the yoghurt thicker.

• It colors the yoghurt.
