- 2.
The calvin cycle occurs in the _______.
-
Thylakoid
-
Stroma
-
Cytoplasm
-
Nucleus
Correct Answer
A. StromaExplanation
The Calvin cycle occurs in the stroma. The stroma is the fluid-filled space within the chloroplasts, specifically in the chloroplast's inner membrane. This is where the second stage of photosynthesis takes place, where carbon dioxide is converted into glucose. The thylakoid, on the other hand, is where the first stage of photosynthesis occurs, involving the absorption of light and the production of ATP. The cytoplasm and nucleus are not directly involved in the Calvin cycle or photosynthesis.Rate this question:

The purpose of photosynthesis is to:
-
Convert solar energy and CO2 to glucose for food
-
Make water
-
Convert solar energy to power cell processes
-
Store electrons to make ATP
Correct Answer
A. Convert solar energy and CO2 to glucose for foodExplanation
Photosynthesis is the process by which plants convert solar energy and carbon dioxide into glucose, which serves as their food source. Through this process, plants capture sunlight using chlorophyll in their leaves and use it to convert carbon dioxide from the atmosphere into glucose molecules. Glucose is a form of stored energy that plants can use for growth, development, and reproduction. Therefore, the purpose of photosynthesis is to convert solar energy and CO2 into glucose for food.Rate this question:

When ATP goes to ADP, this process ___________
-
Converts solar energy to chemical
-
Forms a new ATP
-
Releases energy by breaking a phosphate bond.
-
Happens only once in an organism
Correct Answer
A. Releases energy by breaking a phosphate bond.Explanation
When ATP goes to ADP, it releases energy by breaking a phosphate bond. This is because ATP (adenosine triphosphate) is a high-energy molecule that stores energy in the form of phosphate bonds. When one of these phosphate bonds is broken, ATP is converted into ADP (adenosine diphosphate) and a free phosphate group, and the released energy is used for various cellular processes. This process is essential for providing energy to cells and is repeated continuously in organisms to sustain their metabolic activities.Rate this question:

Photosynthesis makes _____ gas, which we inhale to breathe with for cellular respiration to occur.
-
Carbon dioxide
-
Nitrogen
-
Fermentation
-
Oxygen
Correct Answer
A. OxygenExplanation
Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. The oxygen produced during photosynthesis is released into the atmosphere and is essential for cellular respiration to occur in living organisms, including humans. During cellular respiration, oxygen is used by cells to break down glucose and produce energy. Therefore, the correct answer is oxygen.Rate this question:

Photosystem 1 and photosystem 2 are light __________________ reactions.
-
Indepedent
-
Dependent
-
Obsessed
-
Intensity
Correct Answer
A. DependentExplanation
Photosystem 1 and photosystem 2 are light-dependent reactions. This means that these reactions require light energy in order to occur. Light is absorbed by the pigments in the photosystems, which then initiate a series of electron transfer reactions. These reactions ultimately result in the production of energy-rich molecules such as ATP and NADPH, which are used in the process of photosynthesis. Thus, the correct answer is "dependent".Rate this question:

The green pigment in the chloroplast is called _________________.
-
Chlorophyll
-
Carotene
-
Slime
-
Leaf color
Correct Answer
A. ChlorophyllExplanation
Chlorophyll is the correct answer because it is the green pigment found in chloroplasts, which are responsible for photosynthesis in plants. Chlorophyll absorbs light energy and converts it into chemical energy, playing a crucial role in the process of photosynthesis. It gives plants their green color and is essential for their survival. Carotene is another pigment found in plants, but it is responsible for orange and yellow colors, not green. Slime and leaf color are not correct as they do not refer to the specific pigment in question.Rate this question:

Aerobic respiration is different from anaerobic because it requires _______________ to occur.
-
Carbon
-
Glucose
-
Oxygen
-
Carbon dioxide
Correct Answer
A. OxygenExplanation
Aerobic respiration is a process that occurs in the presence of oxygen. It is different from anaerobic respiration because anaerobic respiration can occur without the need for oxygen. Oxygen plays a crucial role in the breakdown of glucose molecules during aerobic respiration, producing carbon dioxide as a byproduct. Therefore, the correct answer is oxygen.Rate this question:

Many plants in the room will decrease the level of ________ from the air, but increase the level of _____________.
-
Oxygen, nitrogen
-
Carbon dioxide, oxygen
-
Carbon dioxide, nitrogen
-
Water, carbon dioxide
Correct Answer
A. Carbon dioxide, oxygenExplanation
Plants undergo photosynthesis, a process where they take in carbon dioxide from the air and release oxygen. Therefore, having many plants in a room will decrease the level of carbon dioxide from the air and increase the level of oxygen.Rate this question:

Anaerobic respiration includes both alcoholic and ____ _____ fermentation.
-
Lactic acid
-
Citric acid
-
Aerobic acid
-
Pyruvic acid
Correct Answer
A. Lactic acidExplanation
Anaerobic respiration includes both alcoholic and lactic acid fermentation. This means that in the absence of oxygen, organisms can undergo anaerobic respiration and produce either alcohol or lactic acid as byproducts. Lactic acid fermentation occurs in muscle cells during intense exercise when oxygen supply is limited. It is also used in the production of certain foods like yogurt and sauerkraut. Therefore, lactic acid is the correct answer as it completes the statement and accurately describes one of the types of fermentation in anaerobic respiration.Rate this question:
