3rd Nine Weeks Test Flashcards
interphase
DNA is replicated
prophase
nuclear membrane disintegrates, nucleolus disappears, chromosomes condense, mitotic spindle forms between poles
cytokinesis
two identical cells
cell membrane
controls what enters and leaves the cell; found in every type of cell
carbohydrate chains
found on the plasma membrane helps identify chemical signals outside the cell and is involved in cell to cell recognition
cholesterol
helps to stabilize the membrane, is non polar and found between the layers of phospholipids
diffusion
movement of molecules from an area of high concentration to an area of low; (passive) no energy required
osmosis
specific to water movement
cells shrink
hypertonic
cells swell
hypotonic
photosynthesis
anabolic; it builds glucose molecules and releases oxygen
phase 1
light dependent; thylakoids; water molecules split; ATP and NADPH are released into the storm for use in stage 2
chemiosmosis
hydrogen molecule moves down their concentration gradient into the stroma via ion channels
phase 2
calvin cycle; light independent; stroma; CO2 combined with other organic compounds (carbon fixation); sugars and other compounds are formed during this stage
photosynthesis produces
the substrates needed for cellular respiration
