Question:
homeostasis
Answer:
process by which organisms maintain a relatively stable internal environment
Question:
simple diffusion (passive transport)
Answer:
Passive movement from high to low concentration (ex. drop of ink in beaker of water)
- / 4
Question:
facilitated diffusion
Answer:
The process of moving impermeable molecules across a membrane using channels or pores
Question:
active transport
Answer:
Non-spontaneous process process that requires cells to do work to move the ions "uphill" against the concentration gradient.
Question:
Phagocytosis
Answer:
process in which extensions of cytoplasm surround and engulf large particles and take them into the cell
- / 4
Question:
Pinocytosis
Answer:
process by which a cell takes in liquid from the surrounding environment
Question:
Exocytosis
Answer:
a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
Question:
Endocytosis
Answer:
process by which a cell takes material into the cell by infolding of the cell membrane
Question:
Osmosis
Answer:
diffusion of water across a selectively permeable membrane 3 / 4
Question:
light-dependent reactions
Answer:
"Step 1 of Photosynthesis" chlorophyll and other pigments on the thylakoids membranes use absorbed protons from light to break water and excite one of the water's electrons.
Question:
NADPH
Answer:
a type of molecule called an electron career- is adapted to move an electron from one reaction to another
Question:
Calvin Cycle
Answer:
"Step 2 of Photosynthesis"(light-independent reactions) occurs in the storm of chloroplast. The plant uses the energy from ATP and the electron from NADPH to build sugars out of CO2.
