Biology FALL Semester Day 2 Review 24-25

Front

What is the average amount of energy transferred from one trophic level to the next?

Back

10% of energy is transferred from one trophic level to the next in an ecosystem.

Front

What process do plants use to convert CO2 into sugar and oxygen?

Back

Photosynthesis is the process by which plants use CO2 to make sugar and oxygen.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes decrease the activation energy of reactions, making them occur more easily.

Front

What are the three main processes of gene expression?

Back

The three main processes are DNA replication, transcription, and translation.

Front

What is DNA replication?

Back

DNA replication is the process of copying the DNA molecule to produce two identical DNA strands.

Front

What is transcription in biology?

Back

Transcription is the process of synthesizing RNA from a DNA template.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process of decoding mRNA to synthesize proteins.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to convert CO2 and water into glucose and oxygen.

Front

What is the significance of the 10% rule in ecology?

Back

The 10% rule states that only about 10% of the energy from one trophic level is available to the next level.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.
