Anaerobic Respiration in Plants and Yeast Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is anaerobic respiration in plants and yeast?

It is the release of energy from glucose without using oxygen.

When do plant and yeast cells carry out anaerobic respiration?

They do it when there is little or no oxygen, for example in sealed or wet conditions.

What is the word equation for anaerobic respiration in yeast?

Glucose → ethanol + carbon dioxide + energy.

What is another name for anaerobic respiration in yeast?

It is also called fermentation.

What are the main products of anaerobic respiration in plants and yeast?

They make ethanol and carbon dioxide, and release a small amount of energy.

How is anaerobic respiration in yeast different from anaerobic respiration in animals?

Yeast makes ethanol and carbon dioxide, but animals make lactic acid and no carbon dioxide.

Why does anaerobic respiration in plants and yeast release less energy than aerobic respiration?

Because glucose is only partly broken down to ethanol, not fully to carbon dioxide and water.

How does anaerobic respiration in yeast help in bread making?

The carbon dioxide bubbles make the dough rise, and the ethanol boils off in the oven.

How does anaerobic respiration in yeast help in making beer and wine?

The ethanol made by yeast forms the alcohol, and carbon dioxide can make the drink fizzy.

What happens to yeast cells if too much ethanol builds up during fermentation?

Ethanol is poisonous to yeast, so high levels kill the cells and stop respiration.
