1.
What is one of the reactants for cellular respiration?
Correct Answer
A. Glucose
Explanation
One of the reactants for cellular respiration is glucose. Glucose is a type of sugar that serves as a source of energy for cells. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP (adenosine triphosphate), which is the main energy currency of cells. This process occurs in the mitochondria of cells and is essential for the functioning and survival of organisms.
2.
What are the products for photosynthesis?
Correct Answer
C. Sugar + oxygen
Explanation
During photosynthesis, plants convert carbon dioxide and water into glucose (sugar) and oxygen. This process occurs in the chloroplasts of plant cells, where sunlight is captured and used to convert carbon dioxide and water into glucose. The glucose is then used as a source of energy for the plant, while oxygen is released 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, namely glucose (C6H12O6) and oxygen (O2), are broken down into water (H2O), carbon dioxide (CO2), and energy. This process occurs in the mitochondria of cells and is essential for the release of energy stored in glucose molecules. The energy produced during respiration is used by cells for various metabolic activities.
4.
In cellular respiration what is the correct equation
Correct Answer
C. 6O2+c6H12O6->6CO2+6H2O+energy
Explanation
The given equation 6O2+C6H12O6+energy->6CO2+6H2O represents the process of cellular respiration. In this process, oxygen (O2) and glucose (C6H12O6) are used as reactants to produce carbon dioxide (CO2), water (H2O), and energy. This equation accurately represents the chemical reaction that occurs during cellular respiration in living organisms, where glucose is broken down in the presence of oxygen to release energy.
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 into carbon dioxide and water, releasing energy in the form of ATP. Each molecule of glucose can produce up to 36 ATP molecules through aerobic respiration. This is because aerobic respiration involves several steps, including glycolysis, the Krebs cycle, and the electron transport chain, which together generate a high amount of ATP. 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. This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of sunlight. This equation accurately represents the inputs and outputs of photosynthesis, showing the conversion of carbon dioxide and water into glucose and oxygen.
7.
What molecule does aerobic respiration use that anaerobic respiration is missing?
Correct Answer
A. Oxygen
Explanation
Aerobic respiration uses oxygen, while anaerobic respiration does not. Oxygen is an essential molecule in the process of aerobic respiration, as it serves as the final electron acceptor in the electron transport chain, allowing for the production of ATP. In anaerobic respiration, alternative molecules such as nitrate or sulfate are used as electron acceptors. Therefore, the key difference between aerobic and anaerobic respiration lies in the presence or absence of oxygen as the final electron acceptor.
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 plants and animal cells have mitochondria and therefore have the ability to undergo cellular respiration. This process is essential for the production of ATP, the main energy currency of cells.
9.
What molecules belong in the box of the diagram?
Correct Answer
C. 1 respiration; 2 pHotosynthesis
Explanation
The correct answer is 1 respiration; 2 photosynthesis. This is because respiration is the process by which organisms convert glucose into energy, and photosynthesis is the process by which plants convert sunlight into glucose. Both processes are essential for the survival of organisms and play a crucial role in the carbon cycle.
10.
In cellular respiration energy can be released by breaking down which molecule?
Correct Answer
C. Glucose
Explanation
Glucose is the correct answer because it is the main molecule that is broken down during cellular respiration to release energy. This process occurs in the mitochondria of cells and involves the breakdown of glucose into carbon dioxide and water, along with the production of ATP (adenosine triphosphate). ATP is the main energy currency of cells and is used for various cellular activities. Therefore, glucose serves as the primary source of energy for cellular respiration.
