energy-producing organelles are the ____________
not
it would appear logical the first cell could ___ have started to function from one organelle having formed by accident
ribosomes
the ____________ are responsible for linking amino acids together
the basic unit of life is the cell
the cell theory teaches that
Krebs cycle
the complete process which is needed to product ATP is called
meiosis
the division of the nucleus in reproductive cell is called
the product of ATP decomposition
the energy required for mechanism of active transport comes from
faciliated diffusion, passive difussion, active transport, pinocytosis and phagocytosis
the five transport mechanisms of the cell are:
ribosomes
the organelles that produce proteins used within the cell are the ______________
high
the relative concentration of water in hypotonic solution is
double layer of phospholipids
the x\cell membrane is made up of a ____________________________________________________
endoplasmic reticulum
tubes serving as transportation channels
osmosis
water can move freely through the embrane from a higher to lower concentration in a difussion process called
it will gain water and may burst
when an animal cell is placed in a hypotonic solution,
active transport
when the cell concentrates potassiumwithin, against the natural tendency of matter, it is performing ___________
nucleolus
production of ribosomes
ADp or glucose
the energy molecule ATP is a produce of the reactant
ATP
the energy producing or energy-storing molecule is called _______
semi permeable
the plasma membrane allows some molecular species to enter and excludes others, it is therefore referred to as a _________________________ membrane
a plasma membrane
is made up of phospholipid and protiens and is a selective membrane
protein
Amino acids are linked together to form
the molecules are insoluble
Faciliated diffusion is necessary when
they are nonpolar(no charge) and soluble
Oxygen and carbon dioxide pass through the plasma membrane because
creation
a reasonable and logical alternative to evolution of a cell is ___________
isotonic,
a water solution that has the same salt concentration as the cells is said to be __________.
required
all the organelles within a cell are
centrioles
forms fibers to seperate chromosomes evenly
pyruvic acid
glycolysis ends in the production of ______________________
a cell wall
has cellulose and gives strength to the cell
a plant cell
has a cell plate and no centrioles in cell division, it hasa a prensnce of cell wall plus plasma membrane and it has chloroplast and plastids
an animal cell
has no cell wall, only plasma membrane, no large vacuoles, only small ones, no clorophyll only chloroplasts and has a cleavage furrow plus centrioles in cell division
