Energy Unit Review Questions -9th grade

Front

What is Glycolysis?

Back

Glycolysis is the first step of cellular respiration where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the part of photosynthesis that captures and transfers light energy to molecules like ATP and NADPH.

Front

Why do most plants appear green?

Back

Most plants appear green because chlorophyll does not absorb green light; instead, it reflects it.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants), such as herbivorous ducks.

Front

What is another name for glucose?

Back

Another name for glucose is sugar.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that captures light energy for photosynthesis, primarily absorbing blue and red light.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy for various cellular processes.

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.

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.
