,The nucleus is essential for function and survival of the cell.
Mitochondria are known as the power plants of the cell because they
extract energy from organic compounds.
Cell plasma membrane is formed by a lipid bilayer, with specific membrane
functions carried out by bound and transmembrane
proteins.
Cell-to-cell communication utilizes chemical messenger systems that release
secretions into extracellular fluid.
Aerobic metabolism provides energy by combining hydrogen and oxygen to
form water.
Exocytosis is important in removing cellular debris and releasing
synthesized substances into the extracellular fluid.
Membrane potentials are generated and conducted by diffusion of current-
carrying ions.
Epithelial tissues are classified according to the shape of the cells and
the number of layers.
Simple epithelium is a type of epithelial tissue where cells are in contact
with intercellular matrix; some do not extend to surface.
Stratified epithelium is a type of epithelial tissue with a single layer of cells;
all cells rest on basement membrane.
,Glandular epithelium arises from surface epithelia and underlying connective
tissue.
Pseudostratified epithelium is a type of epithelial tissue with multiple layers of cells;
the deepest layer rests on basement membrane.
Fibroblasts in connective tissue are responsible for the synthesis of
collagen, elastin, and reticular fibers.
Smooth muscle is also known as involuntary muscle and differs by
having dense bodies attached to actin filaments.
Ribosomal RNA (rRNA) performs the function of providing the site where
protein synthesis occurs.
Lysosomes are organelles responsible for the breakdown and
removal of foreign substances and worn-out cell parts.
Peroxisomes are involved in the impairment of cellular functions
when their function is compromised.
Protein synthesis involves copying and carrying DNA instructions.
Calcium bonds are stored in mitochondria for muscle contractions.
Cell gap junctions accumulate chemical messengers for effective
signaling.
, Ion channel neurotransmission is responsible for generating and conducting
membrane potentials.
Collagen is synthesized by fibroblasts in connective tissue.
Cellular debris is removed by exocytosis.
ATP is involved in aerobic metabolism by having its
phosphate bonds removed.
Inability to transport cellular products an inability to transport cellular products across the cell
membrane.
Insufficient energy production insufficient energy production within a cell.
Accumulation of free radicals accumulation of free radicals in the cytoplasm.
Decreased sperm motility a finding that is thought to underlie the couples inability
to become pregnant.
Defective cellular components in sperm Ribosomes, Microtubules, Mitochondria,
Microfilaments.
True statement of glycolysis Glycolysis occurs in cells without mitochondria.
