1. Within liver cells, glycogen can be decomposed to yield
glucose. For this process to occur, which substance must also
be present?
• Answer✅: Glucagon and epinephrine
• Rationale: Glucagon (released by the pancreas when blood glucose is low)
and epinephrine (released by adrenal glands during stress) trigger
glycogenolysis, the breakdown of stored glycogen into glucose in the liver.
2. At which phase of meiosis does crossing over occur?
• Answer✅: Prophase 1
• Rationale: Crossing over occurs during Prophase I of meiosis when
homologous chromosomes pair up (synapsis) and exchange genetic material,
which increases genetic diversity.
3. Which cellular process results in the formation of sugar
from carbon dioxide?
• Answer✅: Calvin cycle
• Rationale: The Calvin cycle is the light-independent phase of photosynthesis.
It takes place in the stroma of chloroplasts and uses carbon dioxide, ATP, and
NADPH to produce G3P, a sugar precursor.
4. What is the name for the small, tail-like projection from the
cellular membrane that is used for locomotion?
• Answer✅: Flagella
• Rationale: A flagellum (plural: flagella) is a long, whip-like appendage that
rotates or beats to propel a cell forward, commonly found in sperm cells and
many bacteria.
