Rated A+
Most of the cell membrane's specific functions are controlled by: -
ANSWER-Proteins
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.
What is RNA? -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? -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? -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? -ANSWER-Translation is the process by which a
protein is synthesized from the information contained in a molecule of
