QUESTIONS AND DETAILED CORRECT ANSWERS
What is a pyruvate? - Correct 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? - Correct Answer-Ribosomes
What is the structural and functional unit of life? - Correct Answer-The cell
What is a prokaryotic cell? - Correct Answer-A cell that lacks a true nucleus and membrane-
bound organelles
What is a eukaryotic cell? - Correct Answer-A cell that contains a nucleus and membrane-
bound organelles
Most of the cell membrane's specific functions are controlled by: - Correct Answer-Proteins
,Alcoholic Fermentation is a form of: - Correct Answer-Anaerobic Respiration
Phagocytosis is a form of: - Correct Answer-Endocytosis
What is cytokinesis? - Correct Answer-The division of cytoplasm into two identical daughter
cells, which occurs during the telophase stage of mitosis.
What is a haploid cell? - Correct Answer-A cell that contains one set of chromosomes
What is a diploid cell? - Correct Answer-A cell that contains two sets of chromosomes
What is chromatin? - Correct Answer-The substance of which eukaryotic chromosomes are
composed, consisting of mostly proteins, DNA, and RNA.
What is a centriole? - Correct 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? - Correct Answer-A structure carrying genes is a linear sequence,
found in the nucleus, consisting of DNA and protein.
What is DNA? - Correct 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.
, What is RNA? - Correct Answer-A single-stranded nucleic acid molecule involved in protein
synthesis. It is responsible for carrying the genetic code transcribed for DNA to specialized
sites within the cell where the information is translated into protein composition.
What is a nucleotide? - Correct Answer-A nucleotide is the basic building block of nucleic
acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists
of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate
group and a nitrogen-containing base.
What is transcription? - Correct Answer-Transcription is the process by which the
information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). ...
This complex initiates transcription, and the RNA polymerase begins mRNA synthesis by
matching complementary bases to the original DNA strand.
What is translation? - Correct Answer-Translation is the process by which a protein is
synthesized from the information contained in a molecule of messenger RNA (mRNA).
Translation occurs in a structure called the ribosome, which is a factory for the synthesis of
proteins
What is endocytosis and exocytosis? - Correct Answer-Endocytosis is the process of
capturing a substance or particle from outside the cell by engulfing it with the cell
membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing
with the plasma membrane and releasing their contents to the outside of the cell
What is a chromotid? - Correct Answer-each of the two threadlike strands into which a
chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
