Biol 21 SJSU Exam 1 (Hamed Mouseghy)
peptide bond
Bonds that connect amino acids.
Carbohydrates are composed of
C, H, O (carbon, hydrogen, oxygen)
Nucleic Acids are found in
DNA and RNA
Hypertonic
Having a higher concentration of solute than another solution.
Hypotonic
Having a lower concentration of solute than another solution
isotonic
Having the same solute concentration as another solution.
Exocytosis
Inside cell to outside (uses atp)
Most common elements found in humans
O, C, H, N (Oxygen, Carbon, Hydrogen, and Nitrogen)
Endocytosis
Outside of cell to inside (uses atp)
H-Bonds
accounts for properties of water, dna, protein
Ion
an atom that can gain or lose electrons
connective tissue
binds, supports, protects
muscle tissue
contracts
Nucleus
control center, contains DNA
nervous tissue
detects stimuli and sends electrical impulses
The random movement of solutes from an area of high concentration to an area of low concentration is called
diffusion
4 types of tissue
epithelial, connective, muscle, nervous
what kind of protein is collagen
fibrous (support)
what kind of proteins are keratin
fibrous (support)
DNA stores
genetic information
What kind of protein is hemoglobin?
globular (functional)
What kind of proteins are enzymes
globular (functional)
What kind of proteins are plasma
globular (functional)
different number of neutrons
isotope
Fructose and glucose are what type of saccharides
monosaccharides
Osmosis
movement of water through passive transport
Four defining traits of humans
opposable thumbs, capacity for language, large brain, bipedalism
Amino acids are the smallest unit of a _______
protein
Polypeptide=
protein
facilitated diffusion needs _____ and does not need _____
protein, atp
RNA codes for
proteins
active transport
requires energy (ATP), solute goes from low concentration to high.
Smooth ER has no
ribosomes
Tissue
specialized cells that perform a common function
Three types of epithelial tissue
squamous (lungs, blood vessel) , cubodial (kidneys, glands) , columnar (stomach, intestines)
Plasma membrane
stores lipids and lines the cell
Rough ER
synthesizes proteins and has ribosomes
Homeostasis
the body's mechanism of staying in a stable, livable state (Neutral State)
