AC-HPAT Prep (Biology, Chemistry, Physics, Math)- Q&AMost of the cell membrane's specific functions are controlled by: Correct
Ans - Proteins
Alcoholic Fermentation is a form of: Correct Ans - Anaerobic
Respiration
Phagocytosis is a form of: Correct Ans - Endocytosis
What is a pyruvate? Correct Ans - 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 Ans - Ribosomes
What is the structural and functional unit of life? Correct Ans - The cell
What is a prokaryotic cell? Correct Ans - A cell that lacks a true
nucleus and membrane-bound organelles
What is a eukaryotic cell? Correct Ans - A cell that contains a nucleus
and membrane-bound organelles
What is cellular respiration? Correct Ans - 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? Correct Ans - A form of cellular
respiration that does not involve oxygen.
What is aerobic respiration? Correct Ans - 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: Correct Ans - Diffusion, Osmosis, Active Transport,
and Passive Transport.
Prokaryotes often reproduce by: Correct Ans - Binary Fission
What is binary fission? Correct Ans - A form of asexual reproduction in
which the parent divides into two identical halves.
What is cytokinesis? Correct Ans - The division of cytoplasm into two
identical daughter cells, which occurs during the telophase stage of mitosis.

What is chromatin? Correct Ans - The substance of which eukaryotic
chromosomes are composed, consisting of mostly proteins, DNA, and RNA.
What is a centriole? Correct Ans - 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 Ans - A structure carrying genes is a
linear sequence, found in the nucleus, consisting of DNA and protein.
What is DNA? Correct Ans - 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 Ans - 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.
