What is parasitism?

Back

Parasitism is a type of symbiotic relationship where one organism (the parasite) benefits at the expense of another organism (the host), causing harm to the host.

Front

What is mutualism?

Back

Mutualism is a symbiotic relationship where both organisms involved benefit from the interaction.

Front

What is commensalism?

Back

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.

Front

What biomolecule do enzymes belong to?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in biological processes.

Front

What is cellular respiration?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for chemical reactions, allowing them to occur more quickly and efficiently.

Front

What is the difference between mutualism and parasitism?

Back

In mutualism, both organisms benefit, while in parasitism, one organism benefits at the expense of the other.

Front

Give an example of commensalism.

Back

An example of commensalism is barnacles attaching to whales; barnacles benefit by getting a place to live, while whales are not significantly affected.

Front

What is the significance of cellular respiration in living organisms?

Back

Cellular respiration is crucial for providing energy (ATP) needed for various cellular processes and functions.
