🎯#4 Final/Keystone: Bioenergetics (Cell Energy)

Front

What is bioenergetics?

Back

Bioenergetics is the study of how energy flows through living systems, particularly in relation to cellular processes such as respiration and photosynthesis.

Front

What is the primary function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, where they produce ATP (adenosine triphosphate) through cellular respiration.

Front

What do plants produce during photosynthesis?

Back

Plants produce glucose (sugar) and oxygen during photosynthesis.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to convert it into chemical energy.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions in photosynthesis that convert carbon dioxide and other compounds into glucose.

Front

What are energy carriers?

Back

Energy carriers are molecules that accept high-energy electrons and transfer them to other molecules, such as NADP+ converting to NADPH.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is released as a byproduct of photosynthesis, specifically from the splitting of water molecules during the light reactions.

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

How do plants and animals differ in energy production?

Back

Plants produce their own energy through photosynthesis, while animals obtain energy by consuming plants or other animals.

Front

What is the light-dependent reaction?

Back

The light-dependent reactions are the first stage of photosynthesis, where light energy is converted into chemical energy (ATP and NADPH) and oxygen is released.
