Unit 3 - Cellular Energy Practice & Review

Front

What type of solution is a cell in when it gets bigger than normal while in tap water?

Back

Hypotonic solution: A solution with a lower concentration of solutes compared to the inside of the cell, causing water to enter the cell and make it swell.

Front

Where does the Calvin Cycle take place within the chloroplast?

Back

Stroma: The fluid-filled space in the chloroplast where the Calvin Cycle occurs, utilizing ATP and NADPH to convert carbon dioxide into glucose.

Front

What are the reactants in cell respiration?

Back

Oxygen and sugar: These are the substances that are consumed during cellular respiration to produce energy (ATP), carbon dioxide, and water.

Front

The first step in photosynthesis is -

Back

The light dependent reaction: This process occurs in the thylakoid membranes of chloroplasts, where sunlight is captured and converted into chemical energy.

Front

Where does Kreb's Cycle occur?

Back

Mitochondria: The Kreb's Cycle, also known as the citric acid cycle, takes place in the mitochondrial matrix, producing energy carriers for the electron transport chain.

Front

Define cellular respiration.

Back

Cellular respiration: A metabolic process that converts glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is photosynthesis?

Back

Photosynthesis: The process by which green 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 role of ATP in cellular processes?

Back

ATP (Adenosine Triphosphate): The primary energy carrier in cells, providing energy for various biological processes, including muscle contraction and active transport.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen, resulting in less energy production and byproducts like lactic acid or ethanol.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll: A green pigment found in chloroplasts that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.
