Cellular Respiration and Photosynthesis Flashcard

Front

What is the process by which plants convert sunlight into chemical energy?

Back

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the primary molecule used by cells for energy?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is the process called when molecules move from an area of high concentration to an area of low concentration?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, resulting in an even distribution.

Front

As the hydrogen ions move through a channel in the ETC, ATP is made using the transport mechanism known as ____

Back

Facilitated diffusion is the process by which hydrogen ions move through a channel in the electron transport chain (ETC) to generate ATP.

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are carbon dioxide (CO2), water (H2O), and ATP.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that occurs in the cytoplasm, breaking down glucose into pyruvate and producing a small amount of ATP.

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 the role of NADH in cellular respiration?

Back

NADH is an electron carrier that transports electrons to the electron transport chain, playing a crucial role in ATP production.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.
