Exploring Life's Processes and Evolution

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 does photosynthesis contribute to the carbon cycle?

Back

Photosynthesis absorbs carbon dioxide from the atmosphere and converts it into glucose, releasing oxygen as a byproduct.

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the genetic instructions that are transcribed into RNA, which is then translated into proteins.

Front

What is the significance of the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, ensuring proper cell division and function.

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, crucial for growth and repair.

Front

What is the difference between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen using sunlight, while cellular respiration breaks down glucose to release energy, carbon dioxide, and water.

Front

What is an example of a model used to illustrate cellular processes?

Back

A simulation that predicts the effects of errors in mitosis is an example of a model used to illustrate cellular processes.

Front

What is the function of RNA in protein synthesis?

Back

RNA serves as a messenger that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

Explain the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged among the biosphere, geosphere, hydrosphere, and atmosphere, involving processes like photosynthesis and cellular respiration.

Front

What is the role of enzymes in cellular respiration?

Back

Enzymes speed up the chemical reactions involved in cellular respiration, making the process more efficient.
