BIOLOGY (SECOND SEMESTER)
Terms in this set (46)
refers to the substances that needs to be dissolved catalysed or broken down in order to be utilized by the cell.
can be pure or mixtures could also be solid, liquid, gas.
refers to the substances that will dissolve the solute such as water
refers to how solute particles will move through a gas or solution from an area with a higher number of particles while being separated by a membrane.
involves the movement of molecular substance into the cell without expanding energy (ATP).
particles move from high concentration area to low concentration area that does not need intermediary.
movement of solvent particles in semipermeable into high concentration. (dilute - more concentrated solution)
cell shrinking, loss of water.
equal gradient, no changes
cell burst, gain water
movement of specific molecules down a concentration gradient, passing through a membrane via specific carrier protein.
: occurs when ions or molecules are transported across a membrane of higher concentration with the help of enzymes and by expanding energy.
type of active transport wherein the cell absorbs a membrane by vagination to form a vacuole.
expelled outside the cell.
protein that doesn't require energy, can change shape to move the particles across the plasmic membrane.
large small molecules from pure synthetic substance that contribute to living cells.
refers to pure natural substance essential to maintaining life of living organism
main ingredient in photosynthesis, glycolic, kreb's cycle to generate energy.
for aerobic phase of cellular respiration of living things
important to ATP energy production and other metabolic production
forms the basic structure of proteins, amino acids and nucleic acid.
key component of teeth and bone structure of help in muscle nerve central
main unit of energy for cells, P in ATP.
constitue proteins and nucleic acid, enhances oxygen.
substance formed from the union of two elements.
Types of Inorganic compound
compounds without carbon
product of hydrogen and oxygen, universal solvent.
sour, involved in acid catalysis chemical reaction, acetic acid - vinegar, ascorbic acid - vitamin c
taste bitter and are the compound for accepting ion in chemical reactions, has slippery qualities.
positive (cations) negative (anions), salts or ions can conduct electricity ex. NaCl transmit electric impulses to nerves and muscle cells.
required for photosynthesis.
Types of Organic compound
compound with carbons
large macromoleculeswith amino acids as their basic unit.
building blacks of proteins, forms polypeptide
made up of amino acids, accelerate chemical reactions
macromolecules, main energy source for the body, form from carbon, hydrogen and oxygen bonds.
are the simpliest form of sugar and they are usually colorless and can dissolve in water.
two simple sugars joined by dehydration
Ex. sucrose from glucose and fructose
Ex. lactose from galactose and glucose.
3 or more sugar unit, their role is for long term storage reserve of energy.
Ex. starches, glycogen, cellulose, chitin.
formed from carbon , hydrogen and oxygen bonds linked into chains by fatty acid
: energy storage, insulation, enclose membrane serves as solvent for fat soluble vitamins and hormones.
Ex. Glycerol, triglyceride, chloresterol
composed of 3 substances adenine, ribose, phosphate group.
: cellular respiration (aerobic) electron transfer chain, glycolysis, kreb's cycle.
