EXAM QUESTIONS
QUESTION 1
What is the basic unit of all living things?
CORRECT ANSWER
Cells
RATIONALE: The cell is the basic unit of all living things because it is the smallest structure that can carry out all the
essential functions necessary for life, including reproduction, metabolism, and response to stimuli. All living organisms, from
single-celled bacteria to complex multicellular organisms like humans, are composed of cells that work together to form
tissues, organs, and systems.

, QUESTION 2
What is the basic building block of a protein?
CORRECT ANSWER
Amino Acids
RATIONALE: Amino acids are the correct answer because they are the individual units that are linked together in a specific
sequence to form a protein, which is essentially a long chain of these building blocks. This sequence of amino acids
determines the unique 3D structure and function of the resulting protein, making them the fundamental components that
give proteins their specific characteristics.
QUESTION 3
What is an Enzyme?
CORRECT ANSWER
Proteins that act as a catalyst in life processes
RATIONALE: This definition is correct because enzymes are biological molecules that speed up chemical reactions in living
organisms, and their primary function is to act as catalysts, allowing life processes to occur efficiently and sustainably. The
key concept here is that enzymes lower the activation energy required for a reaction to occur, making it possible for these
processes to take place at a faster rate without being consumed by the reaction itself.
QUESTION 4
How do Enzymes work?
CORRECT ANSWER
- Increase the rate of chemical reactions without being used up
- Have an active site where the substrate binds to carry out a reaction
RATIONALE: This answer is correct because enzymes function as catalysts, meaning they accelerate chemical reactions
without being consumed or altered in the process, allowing them to be reused multiple times. The active site on an enzyme
molecule is crucial for this function, as it specifically binds to the substrate, positioning it for optimal reaction conditions and
facilitating the chemical transformation without being chemically altered itself.

, QUESTION 5
What factors influence Enzyme function?
CORRECT ANSWER
- Temperature
- pH
- Regulatory Molecules
RATIONALE: The factors listed influence enzyme function because they affect the enzyme's ability to bind to its substrate,
which is essential for catalysis to occur. Temperature, pH, and regulatory molecules like inhibitors or activators can alter the
enzyme's conformation, charge, or activity, thereby impacting its effectiveness as a catalyst.
QUESTION 6
What role do Lipids play in living things?
CORRECT ANSWER
- Provide Insulation and long-term storage
- Essential part of cell membrane (phospholipids)
RATIONALE: This answer is correct because it highlights the two primary functions of lipids in living organisms: providing
insulation and long-term storage, which relates to their role in energy storage and maintaining cell structure, and being an
essential part of the cell membrane, specifically as phospholipids, which form the phospholipid bilayer, the structural basis
of cell membranes. By mentioning both functions, the answer demonstrates a comprehensive understanding of the diverse
roles lipids play in maintaining cellular integrity and function.
QUESTION 7
Arrange these terms from least to greatest: Tissue, Organ, Organelle, Cell, Organism
CORRECT ANSWER
Organelle--> Cell--> Tissue--> Organ--> Organism
RATIONALE: The correct sequence is based on the hierarchical organization of living structures, with each level consisting
of multiple instances of the previous level. This hierarchy starts with the basic building block of life, the cell, which
combines to form tissues, which in turn form organs, which ultimately form the organism.
