Anaerobic Respiration 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 and when does it occur?

Anaerobic respiration occurs when oxygen is not available. It involves the incomplete breakdown of glucose, resulting in less energy transfer compared to aerobic respiration.

What is the equation for anaerobic respiration in muscles?

Glucose → Lactic acid
Or
C6H12O6 → 2C3H6O3

Why do muscles undergo anaerobic respiration during intense exercise?

Muscles undergo anaerobic respiration during intense exercise when there is insufficient oxygen available, leading to the production of lactic acid and causing cramps.

What is anaerobic respiration in yeast called and what are its products?

Anaerobic respiration in yeast is called fermentation. Its products are ethanol, carbon dioxide and energy.

What is the equation for fermentation in yeast?

Glucose → Ethanol + Carbon Dioxide + Energy
Or
C6H12O6 → 2C2H5OH + 2CO2

How is fermentation used in the manufacture of bread and alcoholic drinks?

Fermentation produces carbon dioxide, which causes bread dough to rise, and ethanol, which is the alcohol found in beverages like beer and wine.

What is anaerobic respiration and when does it occur?

Anaerobic respiration occurs when oxygen is not available. It involves the incomplete breakdown of glucose, resulting in less energy transfer compared to aerobic respiration.
