Questions and Answers
- 1.
The main purpose of respiration is for a plant or animal to produce...
- A.
Water
- B.
Carbon Dioxide
- C.
Energy
- D.
AZP
Correct Answer
C. EnergyExplanation
Respiration is the process by which organisms convert glucose and oxygen into energy, carbon dioxide, and water. Energy is the main purpose of respiration as it is needed for various cellular activities such as growth, movement, and reproduction. Through respiration, plants and animals are able to break down glucose and release energy in the form of ATP (adenosine triphosphate), which is used as a source of fuel for cellular functions. Therefore, the correct answer is energy.Rate this question:

In the process of anaerobic respiration, which of the following items is not part of the equation?
- A.
Glucose
- B.
Ethanol
- C.
Oxygen
- D.
Carbon Dioxide
- E.
ATP
Correct Answer
C. OxygenExplanation
In the process of anaerobic respiration, oxygen is not part of the equation. Anaerobic respiration is a metabolic process that occurs in the absence of oxygen, and it involves the breakdown of glucose to produce energy in the form of ATP. Instead of oxygen, anaerobic respiration utilizes alternative electron acceptors such as nitrate or sulfate. The byproducts of anaerobic respiration can vary depending on the organism, but commonly include ethanol and carbon dioxide.Rate this question:

Lactic Acid forms when the muscles respire anaerobically which causes your muscles to get tired.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Lactic acid is indeed formed when the muscles respire anaerobically, meaning without oxygen. This occurs during intense exercise or when the body is not able to supply enough oxygen to the muscles. When oxygen is limited, the muscles switch to anaerobic respiration, which produces lactic acid as a byproduct. The accumulation of lactic acid can lead to muscle fatigue and soreness, causing the muscles to feel tired. Therefore, the statement is true.Rate this question:

Fermentation of yeast leads to bread rising because...
- A.
Alcohol evaporates from the bread.
- B.
Carbon dioxide is used in the fermentation.
- C.
Oxygen bubbles form during fermentation and these make the bread rise.
- D.
Carbon dioxide bubbles form during fermentation and these bubble cause the bread to rise.
Correct Answer
D. Carbon dioxide bubbles form during fermentation and these bubble cause the bread to rise.Explanation
During fermentation, yeast consumes sugar and produces carbon dioxide as a byproduct. The carbon dioxide gas gets trapped within the dough, creating bubbles. These bubbles cause the bread to rise as they expand during baking, resulting in a light and fluffy texture. Alcohol is also produced during fermentation, but it evaporates during the baking process. Oxygen bubbles do not form during fermentation and are not responsible for the bread rising.Rate this question:

C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O + ATP .....is the equation for what?
- A.
Aerobic respiration
- B.
Photosynthesis
- C.
Anaerobic respiration
Correct Answer
A. Aerobic respirationExplanation
The equation C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O + ATP represents the process of aerobic respiration. In this process, glucose (C6H12O6) is broken down in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and ATP (energy). This equation is characteristic of aerobic respiration, which occurs in the presence of oxygen and is the main process by which organisms obtain energy from glucose.Rate this question:

Oxygen debt is...
- A.
The oxygen needed to breathe.
- B.
The oxygen needed to be taken into the body for anaerobic respiration
- C.
The amount of oxygen needed to rid the body of lactic acid.
- D.
The oxygen needed for photosynthesis.
Correct Answer
C. The amount of oxygen needed to rid the body of lactic acid.Explanation
Oxygen debt refers to the amount of oxygen that the body needs to consume after intense physical activity in order to break down lactic acid that has accumulated in the muscles. During anaerobic respiration, the body produces lactic acid as a byproduct. This can lead to muscle fatigue and soreness. Oxygen debt is incurred because the body needs oxygen to convert the lactic acid into carbon dioxide and water, which can be eliminated from the body.Rate this question:

In the production of yogurt, bacteria are dead at a temperature of 4.5oC.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Bacteria are not dead at a temperature of 4.5oC. In fact, many bacteria can survive and even multiply at this temperature. In yogurt production, specific strains of bacteria are added to milk and incubated at temperatures between 40-46oC, which allows the bacteria to ferment the lactose in the milk and produce lactic acid. This process gives yogurt its characteristic texture and tangy flavor. Therefore, the statement that bacteria are dead at a temperature of 4.5oC is false.Rate this question:
-
- 8.
Fruit is added to yogurt and then it goes through inoculation.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because inoculation refers to the process of introducing microorganisms, such as bacteria or yeast, into a substance in order to ferment or culture it. In the given scenario, fruit is added to yogurt, but there is no mention of any intentional introduction of microorganisms. Therefore, the statement is incorrect.Rate this question:

- 9.
Large amounts of energy is produced during both aerobic and anaerobic respiration.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because large amounts of energy are only produced during aerobic respiration. Aerobic respiration occurs in the presence of oxygen and is a more efficient process that produces a larger amount of ATP (adenosine triphosphate), which is the energy currency of cells. On the other hand, anaerobic respiration occurs in the absence of oxygen and produces a smaller amount of ATP. Therefore, only aerobic respiration can generate large amounts of energy.Rate this question:
-
- 10.
Aerobic respiration occurs in the...
- A.
Cytoplasm
- B.
Mitochondria
- C.
Nucleus
Correct Answer
B. MitochondriaExplanation
Aerobic respiration is a process that occurs in the presence of oxygen to produce energy. It involves the breakdown of glucose molecules to release energy in the form of ATP. This process takes place in the mitochondria of cells. Mitochondria are known as the powerhouses of the cell because they are responsible for producing most of the cell's energy through aerobic respiration. Therefore, the correct answer is mitochondria.Rate this question:
-
- 11.
Anaerobic respiration occurs in the...
- A.
Cytoplasm
- B.
Mitochondria
- C.
Nucleus
Correct Answer
A. CytoplasmExplanation
Anaerobic respiration occurs in the cytoplasm. This is because anaerobic respiration is a process that occurs in the absence of oxygen, and the cytoplasm is the site where many cellular metabolic reactions take place. During anaerobic respiration, glucose is broken down into simpler molecules, such as lactic acid or ethanol, and energy is released. This process is important in certain microorganisms and muscle cells when oxygen is not readily available. The mitochondria, on the other hand, are responsible for aerobic respiration, which requires oxygen. The nucleus, on the other hand, is not directly involved in the process of respiration.Rate this question:
