Flashcards in Week 1 Deck (52)
Oxygen, Carbon, Hydrogen, Nitrogen (make up 96% of matter in all living organisms)
Calcium, Phosphorus, Potassium, Sulfur, Sodium, Chlorine, Magnesium
Important Trace Elements
Iron, Zinc, Selenium
Body Mass 65%
Necessary for cellular energy (production of ATP); component of water
Body Mass 18.5%
Primary component of anything organic (carbs, lipids, proteins and nucleic acids)
Body Mass 9.5%
Important for pH balance in the body (pH = power of the hydrogen)
Component of water and organic molecules; necessary for energy transfer and respiration
Body Mass 3.3%
Component of all proteins and nucleic acids (DNA & RNA). It's a waste product.
Component of bones and teeth; required for muscle contraction, nerve impulse transmission, and blood clotting
Main component of phospholipid bilayer; principal component in backbone of nucleic acids; important in energy transfer (part of ATP); component of bones
Principal, positive ion within cells; important in nerve function
Important component of most proteins, stabilizes proteins.
Important positive ion in extracellular fluid; important in nerve function
An important electrolyte. It's the most abundant negative ion in extracellular fluids
Component of many energy-transferring enzymes
Critical component of hemoglobin. We need iron to help carry oxygen through the blood.
Important component of many enzymes and proteins
Divide the DNA
Manager of cell, it contains all the info
Powerhouse of cell, this is where ATP is made
Site of protein synthesis (where proteins meet)
Endoplasmic reticulum (ER)
Works closely with ribosomes, assembly line in plant
Shipping & Receiving (&modify) of protein that was just made; it can synthesize carbohydrates
Has hydrolytic enzymes; it's like a digestive system and known as the janitor in the cell; it breaks down whatever substance it engulfs
When a cell dies, lysosomes explode and eat it all up
Spa in the plant. Detoxifying free radicals. Need peroxisomes to stop oxidization.
Cell or Plasma membrane
55% protein, 25% phospholipid, 13% cholesterol, 4% misc. lipids and 3% carbohydrates.
Channel & Globular proteins
Both integral proteins, responsible for the membrane's special functions. Compact ones may be on cell's surface or inside the lipid bilayer.
Some form selective passageways, others create pores.
Meaning of integral proteins
Those within the cell/plasma membrane
