All things Cellular
This structure surrounds the cell and separates intracellular fluid from extracellular fluid.
What is the plasma membrane?
Protein synthesis is also known by this term.
What is translation?
This tissue type covers body surfaces, lines cavities, and forms glands.
What is Epithelial tissue?
This layer is the most superficial part of the skin and is composed of keratinized stratified squamous epithelium.
What is the Epidermis?
A transport process that uses the sodium gradient established by the sodium-potassium pump to move glucose against its concentration gradient is an example of this type of transport.
What is Secondary Active Transport?
This passive transport process moves water across a selectively permeable membrane from an area of lower solute concentration to higher solute concentration.
What is osmosis?
This amino acid is carried by the initiator tRNA and binds the start codon during translation.
What is methionine?
These cell junctions create an impermeable seal between adjacent cells.
What are Tight junctions?
These receptors detect increases or decreases in body temperature and send information to the hypothalamus during thermoregulation.
What are Thermoreceptors?
These are the four major events of protein synthesis in the correct order.
What are Transcription, RNA Processing and Transit, Translation and Posttranslational Modification?
This organelle is known as the "power house" of the cell because it produces most of the cell's ATP.
What is the mitochondrion?
This phase of the cell cycle is when DNA replication occurs.
What is the S phase?
This type of connective tissue contains parallel collagen bundles and is found in tendons and ligaments.
What is Dense Regular Connective Tissue?
This epidermal layer is found only in thick skin and consists of clear, dead keratinocytes.
What is the Stratum lucidum?
This membrane lines body cavities, consists of mesothelium and connective tissue, and secretes fluid that reduces friction around organs.
What is a Serous Membrane (serosa)?
During protein synthesis, the enzyme responsible for building a complementary mRNA transcript from DNA.
What is RNA Polymerase?
This enzyme separates DNA strands during replication.
What is Helicase?
This cartilage type contains abundant collagen fibers and is found in structures such as intervertebral discs.
What is Fibrocartilage?
These sensory receptors located in the reticular layer respond primarily to pressure and vibration.
What are Lamellated (Pacinian) corpuscles?
This layer of the epidermis contains stem cells responsible for replacing dead keratinocytes and is also involved in vitamin D synthesis.
What is the Stratum Basale?
During translation, this ribosomal site receives an incoming tRNA carrying an amino acid before that amino acid is added to the growing peptide chain.
What is the A (aminoacyl) site?
This term describes DNA replication because each new double helix contains one original strand and one newly synthesized strand.
What is Semi-conservative replication?
In tissue repair, when damaged tissue cannot fully regenerate, fibroblasts fill the area with collagen through this process, producing scar tissue.
What is Fibrosis?
This type of skin cancer arises from melanocytes, metastasizes readily through dermal blood vessels, and is identified using the ABCDE rule.
What is Malignant melanoma?
This type of gland only releases product after apical cells rupture, die and release their interior into the duct. (The sebaceous glands are examples of this.)
What are Holocrine glands?
