1.
What is one of the reactants for cellular respiration?
Correct Answer
A. Glucose
Explanation
Glucose is one of the reactants for cellular respiration because it is broken down in the presence of oxygen to release energy. During cellular respiration, glucose is oxidized to produce carbon dioxide and water, which are byproducts of the process. The energy released from the breakdown of glucose is then used by cells to perform various functions and sustain life.
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 converted into chemical energy. The glucose is then used as a source of energy for the plant, while the oxygen 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 into water (H2O), carbon dioxide (CO2), and energy. This process occurs in the mitochondria of cells and is essential for the release of energy that can be used by the organism 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 represents the correct process of cellular respiration. In cellular respiration, glucose (C6H12O6) and oxygen (O2) are consumed, resulting in the production of carbon dioxide (CO2), water (H2O), and energy. This equation accurately shows the reactants (oxygen and glucose) on the left side and the products (carbon dioxide, water, and energy) on the right side. The addition of "energy" on the right side indicates that cellular respiration is an energy-releasing process.
5.
How much ATP does aerobic respiration produce?
Correct Answer
D. 36 ATP
Explanation
Aerobic respiration is the process by which cells convert glucose into energy in the presence of oxygen. During this process, a total of 36 ATP molecules are produced. ATP (adenosine triphosphate) is the main energy currency of cells. It is produced through a series of reactions in the mitochondria, where glucose is broken down and its energy is captured. The 36 ATP molecules generated in aerobic respiration provide the necessary energy for various cellular activities.
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) with the help of sunlight energy.
7.
Which two things does aerobic respiration use that anaerobic respiration is missing?
Correct Answer(s)
A. Oxygen
C. Exercise
Explanation
Aerobic respiration requires oxygen as the final electron acceptor in the electron transport chain, while anaerobic respiration uses other molecules such as sulfate or nitrate. Additionally, aerobic respiration involves the breakdown of glucose to produce energy, while anaerobic respiration can use other molecules like lactate or ethanol. Exercise is also necessary for aerobic respiration as it increases the demand for oxygen and energy production. On the other hand, anaerobic respiration can occur without exercise.
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 into energy. It occurs in both plant and animal cells. In plant cells, cellular respiration takes place in the mitochondria, while in animal cells it occurs in the mitochondria as well as other parts of the cell. Both plant and animal cells require energy for their metabolic processes, so cellular respiration is essential for their survival. Therefore, the correct answer is both plants and animal cells.
