Unit 2 - Lesson 2: E3/E4

What is Cellular Respiration?

• The process by which cells produce oxygen from water.

• The process by which cells convert carbon dioxide into energy.

• The process by which cells break down glucose to produce ATP, using oxygen.

• The process by which cells release energy by breaking down proteins.

Answer explanation

Cellular respiration is the process by which cells break down glucose to produce ATP, using oxygen. This is essential for energy production in aerobic organisms, making the correct choice the one that describes this process accurately.

What is ATP stand for?

• Adenine Triphosphate

• Adenosine Triphosphate

• Amino Triphosphate

• Adenosine Tetraphosphate

Answer explanation

ATP stands for Adenosine Triphosphate, which is the correct choice. It is a crucial molecule in cellular energy transfer, unlike the other options which are incorrect or do not represent ATP.

What is ATP's role in living organisms?

• ATP stores and provides energy for various cellular processes.

• ATP transports oxygen throughout the body.

• ATP breaks down toxins and waste products.

• ATP carries genetic information between cells.

Answer explanation

ATP, or adenosine triphosphate, is crucial for storing and providing energy for various cellular processes, making it the primary energy currency in living organisms.

In terms of the flow of energy in an ecosystem, what is the process that is complimentary to Cellular Respiration?

Answer explanation

Photosynthesis is the process that is complimentary to cellular respiration. While cellular respiration breaks down glucose to release energy, photosynthesis converts light energy into chemical energy, producing glucose.

What are the TWO INPUTS for Cellular Respiration?

(TWO ANSWERS)

• Oxygen

• Glucose

• Carbon Dioxide

• Water

Answer explanation

The two inputs for cellular respiration are Oxygen and Glucose. Oxygen is essential for the process of aerobic respiration, while Glucose serves as the primary energy source that is broken down to produce ATP.

Since Glucose is one of the inputs needed for Cellular Respiration, what type of Carbon-Based Molecule is GLUCOSE?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acid

Answer explanation

Glucose is a simple sugar and is classified as a carbohydrate. Carbohydrates are essential for energy production in cellular respiration, making glucose a key input in this process.

What are the TWO OUTPUTS for Cellular Respiration?

(TWO ANSWERS)

• Oxygen

• Glucose

• Carbon Dioxide

• Water

Answer explanation

The two outputs of cellular respiration are carbon dioxide and water. During this process, glucose is broken down, releasing energy, and producing these byproducts as waste.

What are the TWO TYPES OF ENERGY that is released during Cellular Respiration?

(TWO ANSWERS)

• ATP

• Electrical

• Heat

• ADP

Answer explanation

During cellular respiration, energy is released in the form of ATP, which is the primary energy currency of cells, and as heat, which is a byproduct of metabolic processes. ADP and electrical energy are not direct products of this process.

What are the THREE PARTS of that makes up the structure for ATP?

• Adenine

• Cytosine

• Ribose

• Three Phosphate Groups

Answer explanation

ATP consists of three main parts: adenine (a nitrogenous base), ribose (a sugar), and three phosphate groups. Cytosine is not a component of ATP, making the correct parts adenine, ribose, and the phosphate groups.

Which of the following is the FIRST STEP for the Process of ATP?

• Energy Added

• ATP is Generated when cells carry out Cellular Respiration

• Energy Released

• ATP becomes ADP when it loses one phosphate group

Answer explanation

The first step in the process of ATP involves adding energy to ADP and a phosphate group, forming ATP. This is essential before ATP can be generated during cellular respiration.
