1.
What is one of the reactants for cellular respiration?
Correct Answer
A. Glucose
Explanation
Glucose is one of the reactants for cellular respiration. It is a simple sugar that is broken down in the presence of oxygen to release energy. During cellular respiration, glucose is oxidized in a series of chemical reactions to produce carbon dioxide, water, and ATP (energy). Therefore, glucose is an essential component for the production of energy in cells through the process of cellular respiration.
2.
What are the products for photosynthesis?
Correct Answer
C. Sugar + oxygen
Explanation
During photosynthesis, plants use carbon dioxide and water to produce glucose (sugar) and oxygen. This process occurs in the chloroplasts of plant cells, where sunlight is absorbed by chlorophyll. The energy from sunlight is used to convert carbon dioxide and water into glucose, which is used as a source of energy for the plant, and oxygen, which is released into the atmosphere as a byproduct. Therefore, the correct answer is "sugar + oxygen".
3.
During respiration, the reactants of photosynthesis are changed into
Correct Answer
A. H2O, CO2, and energy
Explanation
During respiration, the reactants of photosynthesis, such as glucose (C6H12O6) and oxygen (O2), are broken down to produce water (H2O), carbon dioxide (CO2), and energy. This process occurs in the mitochondria of cells and is essential for the release of energy needed for various cellular activities.
4.
In cellular respiration what is the correct equation?
Correct Answer
C. 6O2+c6H12O6->6CO2+6H2O+energy
Explanation
The correct equation for cellular respiration is 6O2+C6H12O6+energy->6CO2+6H2O. This equation represents the process of cellular respiration where oxygen (O2) and glucose (C6H12O6) are broken down in the presence of energy to produce carbon dioxide (CO2) and water (H2O). The release of energy is an essential part of cellular respiration, which is why it is included in the equation.
5.
How much ATP does aerobic respiration produce?
Correct Answer
D. 36 ATP
Explanation
Aerobic respiration is a process that occurs in the presence of oxygen and is the most efficient way for cells to produce energy. During aerobic respiration, glucose is broken down in a series of steps, ultimately leading to the production of ATP. In total, aerobic respiration produces 36 ATP molecules. This is because each molecule of glucose produces 2 ATP through glycolysis, 2 ATP through the Krebs cycle, and 32 ATP through oxidative phosphorylation. Therefore, the correct answer is 36 ATP.
6.
Which is the correct equation for photosynthesis?
Correct Answer
B. CO2+H2O -> C6H12O6+O2
Explanation
The correct equation for photosynthesis is CO2+H2O -> C6H12O6+O2. Photosynthesis is the process by which green plants and some other organisms convert carbon dioxide and water into glucose (C6H12O6) and oxygen (O2) using sunlight as the source of energy. This equation represents the overall reaction of photosynthesis, where carbon dioxide and water are reactants and glucose and oxygen are the products.
7.
What molecules does aerobic respiration use that anaerobic respiration is missing?
Correct Answer(s)
A. Oxygen
C. Exercise
Explanation
Aerobic respiration requires the presence of oxygen, which is used as the final electron acceptor in the electron transport chain. This process allows for the complete oxidation of glucose, resulting in the production of a large amount of ATP. Anaerobic respiration, on the other hand, does not use oxygen and instead utilizes alternative electron acceptors such as nitrate or sulfate. Exercise is not directly involved in the respiration process, but it can increase the demand for oxygen and energy production. Light is not a molecule and is not involved in respiration.
8.
Cellular respiration occurs in which cell type?
Correct Answer
C. Both plants and animal cell
Explanation
Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. It occurs in the mitochondria of cells. Both plant cells and animal cells have mitochondria and therefore are capable of undergoing cellular respiration. Therefore, the correct answer is "both plants and animal cells."
9.
What molecules belong in the box of the diagram?
Correct Answer
D. 1 pHotosythesis; 2 respiration
Explanation
The correct answer is 1 photosynthesis; 2 respiration. This is because photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen, while respiration is the process by which organisms break down glucose to release energy and produce carbon dioxide and water. These two processes are complementary and occur in opposite directions, with photosynthesis occurring in the presence of sunlight and respiration occurring at all times.
10.
QIn cellular respiration energy can be released by breaking down which molecule?
Correct Answer
C. Glucose
Explanation
In cellular respiration, energy can be released by breaking down glucose. Glucose is a sugar molecule that serves as the primary source of energy for cells. During cellular respiration, glucose is broken down in a series of chemical reactions, releasing energy that is used to produce ATP (adenosine triphosphate), the main energy currency of cells. Glucose is a high-energy molecule that provides the necessary fuel for cellular processes.
