Photosynthesis, Cellular Respiration and Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are primarily made of proteins.

Front

What type of biomolecule are enzymes classified as?

Back

Enzymes are classified as proteins.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for a reaction, allowing it to occur more quickly.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, meaning their shape changes and they lose their functionality.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the equation for photosynthesis?

Back

carbon dioxide + water + sunlight -> glucose + oxygen.

Front

What are the two main stages of photosynthesis?

Back

The two main stages are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the equation for cellular respiration?

Back

oxygen + sugar -> carbon dioxide + water + energy.

Front

What are producers in an ecosystem?

Back

Producers are organisms that can make their own food, typically through photosynthesis, such as plants.
