5.MIT Biology Exam 2025 | 150 Questions and Answers
1. Describe the role of ribosomes in the rough endoplasmic reticulum.
Ribosomes on the rough ER detoxify harmful substances in the
cell.
Ribosomes on the rough ER are involved in the replication of DNA.
Ribosomes on the rough ER produce lipids for energy storage.
Ribosomes on the rough ER are responsible for synthesizing
proteins that are either secreted from the cell or incorporated
into the cell membrane.
2. In an experiment, a researcher adds a catalyst to a reaction mixture. What
is the expected outcome regarding the reaction rate?
The reaction rate will decrease.
The reaction will stop completely.
The reaction rate will remain unchanged.
The reaction rate will increase.
3. What type of bond is formed when atoms share electrons in a molecule?
Covalent bond
Hydrogen bond
, Metallic bond
Ionic bond
4. The wide variety of life on Earth is called
classification
biodiversity
, vertebrates
species
5. Describe the role of metabolism in living organisms.
Metabolism refers only to the breakdown of nutrients in the
digestive system.
Metabolism is solely responsible for energy production in cells.
Metabolism is the process of cellular division and growth.
Metabolism encompasses all chemical processes that build up
and break down materials, providing energy and necessary
components for life.
6. When substances are changed by the breaking and or forming of
chemical bonds, what has occurred?
Enzyme
Chemical bonds
Metabolism
Homeostasis
Chemical reaction
7. Describe the significance of species in biological classification and
interbreeding.
Species are groups of organisms that share the same habitat.
Species are defined by their ability to adapt to different
environments.
Species are fundamental units in biological classification that
represent groups of organisms capable of interbreeding and
producing fertile offspring.
