QUESTIONS AND SOLUTIONS
◉ Alcoholic Fermentation is a form of: Answer: Anaerobic
Respiration
◉ Phagocytosis is a form of: Answer: Endocytosis
◉ What is a pyruvate? Answer: Pyruvate is an important chemical
compound in biochemistry. It is the output of the metabolism of
glucose known as glycolysis. One molecule of glucose breaks down
into two molecules of pyruvate, which are then used to provide
further energy, in one of two ways.
◉ What are the small spherical bodies within a cell where proteins
are assembled according to genetic instructions? Answer:
Ribosomes
◉ What is the structural and functional unit of life? Answer: The cell
◉ What is a prokaryotic cell? Answer: A cell that lacks a true nucleus
and membrane-bound organelles
,◉ What is a eukaryotic cell? Answer: A cell that contains a nucleus
and membrane-bound organelles
◉ What is cellular respiration? Answer: A catabolic pathway for the
production of ATP, in which sometimes oxygen is consumed as a
reactant along with an organic fuel. At times, the process proceeds
without oxygen, but this is less efficient.
◉ What is anaerobic respiration? Answer: A form of cellular
respiration that does not involve oxygen.
◉ What is aerobic respiration? Answer: Form of cellular respiration
which requires oxygen to generate energy.
◉ Name the four types of transport that allow small molecules to
move across the cell membrane: Answer: Diffusion, Osmosis, Active
Transport, and Passive Transport.
◉ Prokaryotes often reproduce by: Answer: Binary Fission
◉ What is binary fission? Answer: A form of asexual reproduction in
which the parent divides into two identical halves.
, ◉ What is cytokinesis? Answer: The division of cytoplasm into two
identical daughter cells, which occurs during the telophase stage of
mitosis.
◉ What is a haploid cell? Answer: A cell that contains one set of
chromosomes
◉ What is a diploid cell? Answer: A cell that contains two sets of
chromosomes
◉ What is chromatin? Answer: The substance of which eukaryotic
chromosomes are composed, consisting of mostly proteins, DNA,
and RNA.
◉ What is a centriole? Answer: a cylindrical organelle near the
nucleus in animal cells, occurring in pairs and involved in the
development of spindle fibers in cell division.
◉ What is a chromosome? Answer: A structure carrying genes is a
linear sequence, found in the nucleus, consisting of DNA and protein.
◉ What is DNA? Answer: A double-stranded, helical nucleic acid
molecule capable of replicating and determining the inherited
structure of a cell's proteins. It makes up the genetic material of
most living organisms and plays a role in determining heredity.
