Cellular respiration is the opposite of what other cellular process?
-
Fermentation
-
Cell division
-
Hydrolysis
-
Photosynthesis
Correct Answer
A. PhotosynthesisExplanation
Cellular respiration is the opposite of photosynthesis because while photosynthesis is the process by which plants convert sunlight into energy-rich molecules, cellular respiration is the process by which cells break down these energy-rich molecules to release energy. In photosynthesis, carbon dioxide and water are used to produce glucose and oxygen, while in cellular respiration, glucose and oxygen are used to produce carbon dioxide, water, and energy. Therefore, photosynthesis and cellular respiration are complementary processes that occur in opposite directions.Rate this question:

Every type of cellular respiration requires oxygen.
-
True
-
False
Correct Answer
A. FalseExplanation
Not every type of cellular respiration requires oxygen. While aerobic respiration does require oxygen, there are other types of cellular respiration, such as anaerobic respiration, that can occur in the absence of oxygen. In anaerobic respiration, cells use other electron acceptors, such as nitrate or sulfate, instead of oxygen. This process is less efficient than aerobic respiration, but it allows cells to still produce energy when oxygen is not available.Rate this question:

What is produced in the alcohol fermentation?
-
Ethanol
-
Glucose
-
Fructose
-
Phenol
Correct Answer
A. EthanolExplanation
Alcohol fermentation is a metabolic process carried out by yeast and some bacteria to produce ethanol. During this process, glucose is broken down into ethanol and carbon dioxide. Ethanol is the main product of alcohol fermentation and is commonly found in alcoholic beverages. Glucose, fructose, and phenol are not directly produced in alcohol fermentation.Rate this question:

What does ATP stands for?
-
Energy
-
Quantity of CO2
-
Quantity of H2O
-
O2
Correct Answer
A. EnergyExplanation
ATP stands for Adenosine Triphosphate, which is a molecule that stores and provides energy for cellular processes in living organisms. It is often referred to as the "energy currency" of the cell because it is used to transfer energy within cells for various metabolic reactions.Rate this question:

Lactic acid is produced through...
-
Fermentation
-
Aerobic respiration
-
Anaerobic respiration
-
Glycolysis
Correct Answer
A. FermentationExplanation
Lactic acid is produced through fermentation. Fermentation is a metabolic process that occurs in the absence of oxygen. During fermentation, glucose is broken down into lactic acid, producing energy in the form of ATP. This process is commonly observed in certain bacteria and yeast, as well as in muscle cells during intense exercise when oxygen supply is limited. It is an anaerobic process that allows cells to continue producing energy in the absence of oxygen.Rate this question:

From the complete oxidation of one glucose molecule to carbon dioxide and oxidation of all the reduced coenzymes which quantity of ATP results?
-
30 or 32
-
50 or 52
-
15
-
3-5
Correct Answer
A. 30 or 32Explanation
The complete oxidation of one glucose molecule to carbon dioxide and the oxidation of all the reduced coenzymes results in the production of either 30 or 32 ATP. This is because the process of cellular respiration involves the conversion of glucose into energy in the form of ATP. The exact number of ATP molecules produced can vary depending on the specific conditions and pathways involved in the process.Rate this question:

Cellular respiration is considered an exothermic redox reaction which releases heat.
-
True
-
False
Correct Answer
A. TrueExplanation
Cellular respiration is a metabolic process in which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. This process involves a series of redox reactions, where electrons are transferred from glucose to oxygen. Exothermic reactions release heat, and cellular respiration is one such reaction. Therefore, it is correct to say that cellular respiration is an exothermic redox reaction that releases heat.Rate this question:
