BIOD 151 EXAM 1: PORTAGE
LEARNING- BIOD 151, 2025/2026 WITH
CORRECT/ACCURATE ANSWERS
What is the function of the extracellular matrix? - CORRECT
ANSWERS- Binds together and regulates many cellular functions
What are the six levels of organization in the body? - CORRECT
ANSWERS- atom, molecule, macromolecule, organelle, cell,
tissue, organ, system of organs, and organism
The necessary life function that protects our internal environment
from our external environment is provided by what system? -
CORRECT ANSWERS- Integumentary system
What is the function of RNA? - CORRECT ANSWERS- decode
messenger RNA and synthesize the formation of peptide bonds
What is the function of endospores? - CORRECT ANSWERS- allows
bacteria to survive in dormant state and preserve DNA while
enduring high stress conditions
What is the function of the Golgi complex? - CORRECT ANSWERS-
receives lipids and proteins from ER and alters the structures and
ships them to other parts of the cell
, What is the function of lysosomes? - CORRECT ANSWERS- contain
digestive enzymes to breakdown waste products and harmful
materials
What is the function of mitochondria? - CORRECT ANSWERS-
convert chemical energy to ATP
What is the function of the plasma membrane? - CORRECT
ANSWERS- regulate the passage of materials that enter and exit
the cell
What is the function of microtubules and microfilaments? -
CORRECT ANSWERS- Microtubules: involved in the movement of
chromosomes during cell division and in the structure if there is
cilia or flagella
Microfilaments: Two intertwined chains of actin that work together
with myosin to cause the formation of two daughter cells
Describe aerobic respiration and the purpose of ATP production -
CORRECT ANSWERS- Aerobic respiration is the process of using
oxygen to create CO2 and ATP. The purpose of ATP production is
to produce as much energy as possible
Explain what happens in Tay-Sachs disease - CORRECT ANSWERS-
One of the normally present digestive enzymes inside lysosomes
is lacking. Thus, a toxic lipid in the brain cells cannot be broken
down. The resulting buildup of lipids in these cells can cause
intellectual disability and death.
