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

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.
