BIOS251 Exam 2 2026 Exam
Questions with 100% Correct
Answers | Latest Update
Metabolism - 🧠 ANSWER ✔✔All of the chemical reactions of the body
Anabolism - 🧠 ANSWER ✔✔Energy-storing (endergonic) synthesis
reactions
•Requires energy input
Catabolism - 🧠 ANSWER ✔✔Energy-releasing (exergonic) decomposition
reactions
,•Breaks covalent bonds
•Produces smaller molecules
Mitosis - 🧠 ANSWER ✔✔Mitosis is a type of cell division in which one cell
(the mother) divides to produce two new cells (the daughters) that are
genetically identical to itself.
Meiosis - 🧠 ANSWER ✔✔a type of cell division that results in four daughter
cells each with half the number of chromosomes of the parent cell
Compare and contrast mitosis and meiosis - 🧠 ANSWER ✔✔-Both involved
in cell division resulting in new cells.
-mitosis produces cells that are genetically identical to the parent cell and
the nucleus divides once.
-Meiosis produces cells that have ½ the number of chromosomes from
each parent cell and the nucleus divides twice.
crossing over - 🧠 ANSWER ✔✔-The sharing of genetic material between
two non-sister chromatids in a homologous pair.
-occurs during prophase I of meiosis before tetrads are aligned along the
equator in metaphase I.
, -occurs when chromosomal homologs exchange information during
metaphase of Meiosis I
Nucleus - 🧠 ANSWER ✔✔Controls cell because it contains DNA, the
genetic code--instructions for making proteins, which in turn determine cell
structure and function
Endoplasmic Reticulum - 🧠 ANSWER ✔✔-Network of connecting sacs and
canals
-Carry substances through fluid cytoplasm
-Two types: rough and smooth
Rough ER - 🧠 ANSWER ✔✔collects, folds, and transports proteins made
by ribosomes, has ribosomes on it
Smooth ER - 🧠 ANSWER ✔✔synthesizes chemicals, produces lipids that
makes up new membrane
Mitochondria - 🧠 ANSWER ✔✔-Powerhouse of the cell
-ATP is created in mitochondria
-Involved with energy-releasing chemical reactions
-Contains one DNA molecule
