Metabolism 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 respiration and what role do enzymes play in it?

Respiration is a chemical reaction that releases energy from glucose molecules. Enzymes help to break down glucose and harness the released energy for the synthesis of new molecules.

How is glucose used in plant and animal cells for storage?

In plant cells, glucose is converted into starch for storage, and in animal cells, it is converted into glycogen.

What is metabolism?

Metabolism is the sum of all chemical reactions in the body, powered by energy from cellular respiration.

What are the two categories of metabolic reactions?

The breakdown of molecules and the synthesis of molecules.

Give examples of the breakdown of molecules during digestion.

Complex carbohydrates are broken down into simple sugars, proteins into amino acids, and lipids into 3 fatty acids and glycerol.

Give examples of the synthesis of molecules.

Simple sugars form complex carbohydrates, amino acids form proteins, and 3 fatty acids plus glycerol form lipids.
