What is passive transport? - ANSWER-The movement of materials across the cell
membrane without using cellular energy, water and small electrically uncharged
molecules, done through osmosis
What is oxidative phosphorylation? - ANSWER-occurs in the mitochondria and is
the mechanism by which the energy produced from carbohydrates, fats, and
proteins is transferred to ATP.
What is endocytosis and exocytosis? - ANSWER-Endo= into the cell (engulf).
Exo= out of the cell (excrete).
,What is active transport? - ANSWER-requires the cell to expend energy (by means
of ATP) to move larger molecules and molecular complexes
What is pinocytosis? - ANSWER-the ingestion of liquid into a cell by the budding
of small vesicles from the cell membrane. (drinking)
How is endocytosis done? - ANSWER-when the substance to be transported is
engulfed by a segment of the plasma membrane, forming a vesicle that moves into
the cell.
What is phagocytosis? - ANSWER-the ingestion of bacteria or other material by
phagocytes and amoeboid protozoans. (eating)
What is receptor-mediated endocytosis? - ANSWER-receptor-mediated
endocytosis to selectively take up specific molecules or complexes of molecules
that cannot diffuse or move through transport proteins
What is diffusion? - ANSWER-The movement of particles from an area of high
concentration to an area of low concentration.
What happens after endocytosis occurs? - ANSWER-lysosomal enzymes process
and digest material
What is osmosis? - ANSWER-diffusion of water across a selectively permeable
membrane
How are cells specialized? - ANSWER-through the process of differentiation or
maturation
, What are the eight specialized cellular functions? - ANSWER-movement,
conductivity, metabolic absorption, secretion, excretion, respiration, reproduction,
and communication
What are the three general components of an eukaryotic cell? - ANSWER-the
plasma membrane, the cytoplasm, and the intracellular organelles.
What causes the release of lysosomal enzemes? - ANSWER-Cellular injury
causing cellular self-digestion
What is the location and function of the nucleus? - ANSWER-the largest
membrane-bound organelle and is found usually in the cell's center. The chief
functions of the nucleus are cell division and control of genetic information.
What is Cytoplasm? - ANSWER-an aqueous solution (cytosol) that fills the space
between the nucleus and the plasma membrane.
What is the endoplasmic reticulum and what does it specialize in? - ANSWER-a
network of tubular channels (cisternae) that extend throughout the outer nuclear
membrane. It specializes in the synthesis and transport of protein and lipid
components of most of the organelles
What is the plasma membrane? - ANSWER-encloses the cell and, by controlling
the movement of substances across it, exerts a powerful influence on metabolic
pathways
What is signal transduction? - ANSWER-The transfer of molecular signals from
the exterior to the interior of a cell. If not done apoptosis occurs
What is protein regulation and what is it composed of? - ANSWER-protein
homeostasis and is defined by the proteostasis network. This network is composed
