Which process occurs in the chloroplast?
-
Photosynthesis
-
Cellular respiration
-
Both photosynthesis and cellular respiration
-
Neither photosynthesis nor cellular respiration
Correct Answer
A. PhotosynthesisExplanation
Photosynthesis is the process that occurs in the chloroplast. It is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. This process takes place in the chloroplasts of plant cells, specifically in the thylakoid membranes. During photosynthesis, light energy is absorbed by chlorophyll, which then initiates a series of chemical reactions that result in the production of glucose and the release of oxygen. Therefore, photosynthesis is the correct answer as it is the primary function of chloroplasts.Rate this question:

Which organism(s) perform cellular respiration?
-
Only animals
-
Only plants
-
Plants and animals
-
All living organisms
Correct Answer
A. Plants and animalsExplanation
Plants and animals both perform cellular respiration. Cellular respiration is the process by which cells convert glucose and oxygen into energy, water, and carbon dioxide. This process occurs in the mitochondria of cells and is essential for the survival and functioning of all living organisms. Plants perform cellular respiration during the night or in the absence of sunlight when they cannot undergo photosynthesis. Animals, on the other hand, rely solely on cellular respiration to obtain energy from their food. Therefore, both plants and animals perform cellular respiration.Rate this question:

How many molecules of glucose can be produced using 12 molecules of carbon dioxide?
-
One
-
Two
-
Six
-
Another amount
Correct Answer
A. TwoExplanation
Glucose has the chemical formula C6H12O6, which means it contains 6 carbon atoms. Each molecule of carbon dioxide (CO2) contains 1 carbon atom. Therefore, to produce one molecule of glucose, 6 molecules of carbon dioxide are needed. Since we have 12 molecules of carbon dioxide, we can produce 2 molecules of glucose.Rate this question:

What is the correct order for the steps in cellular respiration?
-
Glycolysis, electron transport system, Calvin cycle
-
Light reactions, Calvin cycle
-
Light reaction, Calvin cycle, electron transport system
-
Glycolysis, Kreb's cycle, electron transport system
Correct Answer
A. Glycolysis, Kreb's cycle, electron transport systemExplanation
The correct order for the steps in cellular respiration is glycolysis, Kreb's cycle, and electron transport system. Glycolysis is the initial step in cellular respiration where glucose is broken down into pyruvate. The Kreb's cycle follows glycolysis and involves the oxidation of pyruvate to produce energy-rich molecules. Lastly, the electron transport system uses the energy from the previous steps to generate ATP, the main energy currency of the cell.Rate this question:

What process is shown below?
-
Kreb's cycle
-
Calvin cycle
-
Electron transport system
-
None of the above
Correct Answer
A. Calvin cycleExplanation
The process shown in the image is the Calvin cycle. The Calvin cycle is a series of chemical reactions that take place in the chloroplasts of plants during photosynthesis. It converts carbon dioxide into glucose, using ATP and NADPH generated in the light-dependent reactions. This process is essential for the production of carbohydrates, which are used as a source of energy by the plant. The Kreb's cycle and electron transport system are involved in cellular respiration, not photosynthesis.Rate this question:

Which process is shown above?
-
Photosynthesis
-
Cellular respiration
-
Glycolysis
-
Electron transport system
Correct Answer
A. GlycolysisExplanation
The process shown above is glycolysis. Glycolysis is the first step in cellular respiration, where glucose is broken down into pyruvate. It occurs in the cytoplasm of the cell and does not require oxygen. This process produces a small amount of ATP and NADH, which can then be used in the later steps of cellular respiration to produce more energy.Rate this question:
