Detailed Answers (Verified Answers) |Newest
Version!!!
What are the properties of a eukaryotic cell - Answer-•
Well define nucleus.
• cells are larger and have more extensive intracellular
anatomy and organization than do prokaryotes.
• cells bind with deoxyribonucleic acid (DNA) and are
involved in the super coiling of DNA.
• cells have several chromosomes, protein production or
synthesis
. it consists of three components: outer membrane called
plasma membrane, a fluid filling called cytoplasm, and the
intra cellular organs or organelles
How do cells communicate with each other and the
environment outside the cell - Answer-Cells communicate
by using hundreds of signal molecules.
-they display plasma membrane-bound signaling
molecules (receptor) that affect the cell itself and other
cells in direct physical contact
,2|Page
-they affect receptor proteins inside the target cell and the
signal molecule has to enter the cell to bind to them
-they form protein channels (gap juctions) that directly
coordinate the activities of adjacent cells.
responsable for cellular respiration and energy production
- Answer-mitocondria
they provide sites for cellular protein synthesis - Answer-
ribosome
is the largest membrane bound organelle and is usually
found in the cell center, main function is cell division and
control of genetic information - Answer-nucleus
is a small dense structure composed largely of RNA and
combine it with proteins - Answer-nucleolus
are saclike structures that originate from the golgi complex
and contain digestive enzymes - Answer-lysosomes
,3|Page
specializes in the synthesis and transport of the protein
and lipid components of most of the cells organelles -
Answer-endoplasmic reticulum
proteins from the endoplasmic reticulum are processed
and packaged into small membrane - Answer-Golgi
apparatus or complex
membrane organelles that contain several oxidative
enzymes such as catalase and urate oxidase. those
enzymes use oxygen to remove hydrogen in an oxidative
reaction that produces hydrogen peroxide. - Answer-
peroxisomes
it is the gelatinous, semiliquid portion of the cytoplasm.
functions include: intermediary metabolism involving
enzymatic biochemical reactions; ribosomal protein
synthesis and storage of carbohydrates, fat and secretory
vesicles - Answer-cytosol
maintains the cell's shape and internal organization -
Answer-cytoskeleton
, 4|Page
cells secrete local chemical mediators that are quickly
absorbed, destroyed and immobilized. - Answer-paracrine
cancer cells use this form of signaling to stimulate their
survival and proliferation. it function as a component of
normal growth regulatory mechanism. - Answer-autocrine
diffuses across the synaptic cleft and acts on the
postsypnaptic target cells - Answer-neurotransmitter
are released by one set of cells and travel through the
tissue and through the bloodstream to produce a response
in other set of cells - Answer-hormone
proteins float in the fluid lipid bilayer. is a membrane
structure that consists of a variety of individual protein
molecules moving and shifting within a fluid bilayer of
phospholipids. - Answer-fluid mosaic model
second messenger - Answer-are molecules that relay
signals received at receptors on the cell surface
are generated in large numbers when the membrane
bound enzyme is activated, and they then rapidly diffuse
