Question 1
The correct answer for question 1 is c) The net movement of any type of molecule from a region of higher concentration to a region of lower concentration. This is the process of diffusion. In diffusion, particles move from an area of high concentration to an area of low concentration until equilibrium is reached.
Question 2
The correct answer for question 2 is d) Translating and receiving chemical signals. The three-dimensional structure of proteins allows them to interact with other molecules and act as receptors or signaling molecules. This function is not directly related to their structure.
Question 3
The correct answer for question 3 is c) Designed to allow certain substances to enter and certain substances to exit the cell. The plasma membrane of a plant cell is selectively permeable, meaning it regulates the movement of substances in and out of the cell.
Question 4
The correct answer for question 4 is c) Are the inputs of photosynthesis the same as the outputs of respiration? This question will help the student understand if the inputs and outputs of these two processes are interconnected.
Question 5
The correct answer for question 5 is a) The breakdown of glucose. This step, known as glycolysis, is the initial breakdown of glucose during cellular respiration.
Question 6
The correct answer for question 6 is a) Water and carbon dioxide and ATP. In aerobic cellular respiration, glucose is broken down to produce water, carbon dioxide, and ATP (adenosine triphosphate) as energy currency.
Question 7
The correct answer for question 7 is c) Oxygen and glucose (chemical energy). Photosynthesis uses water and carbon dioxide, powered by sunlight energy, to produce oxygen and glucose, which is a form of chemical energy.
Question 8
The correct answer for question 8 is a) ATP stores energy captured from the light-dependent reactions to be used when producing sugars. ATP, or adenosine triphosphate, is responsible for storing energy captured during photosynthesis to be used in other cellular processes.
Question 9
The correct answer for question 9 is b) The cellular process is photosynthesis. The illustration represents the movement of materials involved in the process of photosynthesis.
Question 10
The correct answer for question 10 is c) Energy is released from bonds. When ATP (adenosine triphosphate) is converted to ADP (adenosine diphosphate), energy is released from the phosphate bond.
Question 11
The correct answer for question 11 is b) Glycolysis. Glycolysis is the process of breaking down glucose into pyruvate and is the only step in cellular respiration that takes place in the cytoplasm of a eukaryotic cell.
Question 12
The correct answer for question 12 is b) B. Based on light intensity, chloroplasts' role in photosynthesis is best represented by graph B.
Question 13
The correct answer for question 13 is b) The products of cellular respiration are the reactants of photosynthesis. The products of cellular respiration, such as carbon dioxide and water, are used as reactants in photosynthesis, and the products of photosynthesis, such as oxygen and glucose, are used as reactants in cellular respiration.
Question 14
The correct answer for question 14 is d) Respiration breaks down glucose and releases energy in the form of ATP. Aerobic respiration breaks down glucose and releases energy in the form of ATP (adenosine triphosphate).
Question 15

2. water: a. reactant
3. oxygen: b. product
4. carbon dioxide: a. reactant
Question 16
The correct answer for question 16 is a) to make sugars and store energy. The purpose of photosynthesis is to convert sunlight energy into chemical energy (glucose) and store it for later use.
Question 17
The correct answer for question 17 is c) Does increased activity lead to a higher volume of carbon dioxide produced? The scientist can analyze the volume of carbon dioxide produced during different levels of activity.
Question 18
The correct answer for question 18 is b) a third phosphate group is bonded to an ADP molecule. Cells store short-term energy by bonding a third phosphate group to an ADP molecule, creating ATP (adenosine triphosphate).
Question 19
The correct answer for question 19 is b) Respiration breaks down glucose and releases energy in the form of ATP. Aerobic respiration breaks down glucose and releases energy in the form of ATP (adenosine triphosphate).
Question 20
The correct answer for question 20 is d) the breakdown of glucose. This is the initial step in cellular respiration, where glucose is broken down to release energy.
Question 21
The correct answer for question 21 is d) energy from the Sun, which transforms into chemical energy. Photosynthesis requires energy from the Sun, which is converted into chemical energy stored in glucose.
Question 22
The correct answer for question 22 is b) 6CO2 + 6H2O → C6H1206 + 6O2. This equation summarizes the overall reactions of photosynthesis, where carbon dioxide and water are used to produce glucose and oxygen.
Question 23
The correct answers for question 23 are a) oxygen, c) enzymes, and d) organic molecules. These substances are necessary for the process of aerobic respiration to take place in mitochondria.
Question 24
The correct answer for question 24 is c) starch. Substance W is starch, which is produced during photosynthesis and stored as an energy reserve in plants.
Question 25
The correct answer for question 25 is b) aerobic respiration. Mitochondria are the site of aerobic respiration, so if they are destroyed, the cell's ability to perform aerobic respiration will be most likely be stopped.
