Cell and Cellular Respiration
SURFIN’ THROUGH STAAR
Session 2: Cellular Processes
Background Information: Cell Transport
When molecules move from a high to low concentration it is called moving DOWN the concentration gradient. When molecules move from a low to high concentration it is called moving AGAINST the concentration gradient. When the concentration of a solute is the same throughout a system, the system is at EQUILIBRIUM. What kind of transport DOES NOT require energy? PASSIVE What kind of transport requires energy? ACTIVE Which CELL PART provides the energy for active transport? MITOCHONDRIA Which MOLECULE is produced by mitochondria and provides energy for transport? ATP Movement of molecules FROM a region of HIGH concentration TO a region of LOW concentration = DIFFUSION The movement of molecules FROM a region of HIGH concentration TO a region of LOW concentration with the HELP of carrier proteins or channels = FACILITATED DIFFUSION
Membrane proteins that move molecules across membranes by attaching, changing shape, and flipping to the other side like a revolving door = CARRIER PROTEINS
Membrane proteins that help molecules across membranes by providing a tunnel = PROTEIN CHANNELS The movement of WATER molecules from HIGH concentration to LOW concentration across a cell membrane = OSMOSIS
Stage 3
Stages 1 & 2Which kinds of transport use VESICLES to help molecules across membranes? ENDOCYTOSIS (PHAGOCYTOSIS & PINOCYTOSIS & EXOCYTOSIS
Photosynthesis Chemical Reaction for photosynthesis:
Water + Carbon dioxide à Glucose + Oxygen
6H2O + 6CO2 C6H12O6 + 6O2
Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches
Chloroplast- site of photosynthesis
Cellular Respiration- process that releases energy by breaking down glucose and other food molecules in the presence of oxygen; Aerobic
