-
Animals
-
Fungi
-
All of the above
Correct Answer
A. All of the aboveExplanation
All organisms listed in the options, including plants, animals, and fungi, carry out cellular respiration all the time in all of their cells. Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. This process occurs in the mitochondria of cells and is essential for the production of energy needed for various cellular activities. Therefore, all of these organisms require cellular respiration to survive and function properly.Rate this question:

Which of the following is NOT a true statement about ATP?
-
ATP provides the energy for cells to do what they do; without it nothing would be alive.
-
ATP consists of adenosine and a 3-phosphate ‘tail’
-
ATP is ‘degraded’ (or reduced) to ADP when it releases its energy.
-
Used ATP molecules are discarded (‘thrown away’) by the cell, never to be used again.
Correct Answer
A. Used ATP molecules are discarded (‘thrown away’) by the cell, never to be used again.Explanation
The statement that used ATP molecules are discarded by the cell, never to be used again, is not true. ATP is a molecule that can be recycled and reused by the cell. When ATP is hydrolyzed to ADP, it can be regenerated back to ATP through processes like cellular respiration. Therefore, ATP molecules are not simply thrown away but rather undergo a cycle of synthesis and degradation to provide energy for cellular processes.Rate this question:

Which of the following is true?
-
Amino acids are made of proteins.
-
Polymers are made of monomers.
-
Glycerol is made of fatty acids.
-
Sucrose is made of polysaccharides.
Correct Answer
A. Polymers are made of monomers.Explanation
Polymers are made of monomers because polymers are large molecules made up of repeating subunits called monomers. These monomers are bonded together through chemical reactions, such as dehydration synthesis, to form a long chain-like structure. This process is known as polymerization. Therefore, the statement "Polymers are made of monomers" is true.Rate this question:

Suppose the supplement was exposed to extreme heat before you tested it, and therefore, it did not test positive for protein. What would you likely attribute that to?
-
The nutritional label is a lie
-
Buffers changed the pH of the proteins
-
The proteins were denatured
-
The amino acids never bonded together
Correct Answer
A. The proteins were denaturedExplanation
The correct answer is "The proteins were denatured." Denaturation refers to the process in which the structure of a protein is altered, usually due to extreme heat or other harsh conditions. This can result in the loss of the protein's functional properties, such as its ability to be detected in a protein test. In this case, the extreme heat exposure likely caused the proteins in the supplement to denature, leading to a negative result in the protein test.Rate this question:

The amino acid is to protein as:
-
Triglyceride is to testoterone
-
Hydroxide is to hydrogen
-
Glycogen is to glucose
-
Glucose is to starch
Correct Answer
A. Glucose is to starchExplanation
Glucose is a monosaccharide, which is a simple sugar and the primary source of energy for the body. Starch, on the other hand, is a complex carbohydrate made up of many glucose molecules linked together. Similarly, amino acids are the building blocks of proteins, and proteins are made up of chains of amino acids. Therefore, the relationship between glucose and starch is similar to the relationship between amino acids and proteins.Rate this question:

Which macromolecule provides the majority of quick energy and also the largest percentage of an average human's energy?
-
Carbohydrates
-
Proteins
-
Lipids
-
Nucleic acids (ex: DNA, RNA)
Correct Answer
A. CarbohydratesExplanation
Carbohydrates provide the majority of quick energy and also the largest percentage of an average human's energy.

Which phrase best describes the effect of a catalyst on a chemical reaction?
-
Increases the temperature
-
Increases the volume of reactants
-
Decreases the reaction rate
-
Decreases the activation energy
Correct Answer
A. Decreases the activation energyExplanation
A catalyst is a substance that speeds up a chemical reaction by decreasing the activation energy required for the reaction to occur. Activation energy is the energy needed to start a reaction, and by lowering this energy barrier, a catalyst allows the reaction to proceed more easily and quickly. Therefore, the correct answer is "decreases the activation energy."Rate this question:

Which of the following is NOT true of enzymes?
-
They are specialized proteins.
-
They affect activation energy and reaction rates.
-
They can bend or flex.
-
They must be rebuilt after each use.
Correct Answer
A. They must be rebuilt after each use.Explanation
Enzymes are specialized proteins that act as catalysts in biological reactions. They lower the activation energy required for a reaction to occur, thereby increasing the reaction rate. Enzymes are known to have the ability to bend or flex, which is crucial for their function. However, enzymes are not required to be rebuilt after each use. They can be used repeatedly without being consumed or permanently altered in the reaction process.Rate this question:

Correct Answer
A. ATPExplanation
ATP (adenosine triphosphate) is a molecule that stores readily usable energy for nearly all cell functions. It is often referred to as the "energy currency" of the cell because it provides the energy needed for various cellular processes. ATP is produced during cellular respiration and can be quickly broken down to release energy when needed. It is essential for activities such as muscle contraction, active transport, and synthesis of macromolecules.Rate this question:

Why do you think you and chicken liver share the same enzyme, catalase, in common?
-
Catalase is a bacteria that infects many types of animals, including humans and chickens.
-
"Life" has developed certain structures over millions of years; those that have useful functions tend to be found in many different species--inherited from common ancestors.
-
Catalase is the only useful enzyme, so all living things have it.
-
Human realized catalase works well in themselves and so began injecting it into chickens.
Correct Answer
A. "Life" has developed certain structures over millions of years; those that have useful functions tend to be found in many different species--inherited from common ancestors.Explanation
The answer suggests that the reason why humans and chickens share the same enzyme, catalase, is because of the common ancestry and the development of certain structures over millions of years.

If we didn't have enzymes, which of the following would likely be true?
-
We wouldn't have trillions of chemical reactions happening in our bodies per second.
-
Our body temperature would have to increase dramatically to make reactions happen.
-
This bio class would have been a lot shorter.
-
All of the above
Correct Answer
A. All of the aboveExplanation
If we didn't have enzymes, all of the statements would likely be true. Enzymes are biological catalysts that speed up chemical reactions in our bodies. Without enzymes, the rate of reactions would significantly decrease, resulting in fewer chemical reactions happening per second. To compensate for this, our body temperature would have to increase dramatically to provide the necessary energy for reactions to occur. Additionally, enzymes play a crucial role in digestion, metabolism, and other bodily processes, so without them, the study of biology would be significantly shorter.Rate this question:
