Groups:

(a) Carbohydrates

,

(b) Lipids

,

(c) Proteins

,

(d) Nucleic Acid

• Structural, transport molecules, enzymes, hormones, antibodies

• Cell Membrane only

• Contains/store genetic info. for cell processes; instructions to make proteins

• Long term energy storage

• Nucleus(DNA) and RNA(ribosomes)

• Cell wall, cell membrane

• Cell membrane, all throughout cell(ribosomes/cytoplasm

• Provide energy, quick form

Where do the carbon(C) and hydrogen(H) atoms come from that is used in photosynthesis to make glucose?

Use photosynthesis formula below for reference: 6CO₂ + 6H₂O + Sun → C₆H₁₂O₆ + 6O₂

• Carbon Dioxide(CO2) & Water(H2O)

• Sunlight and H2O

• Glucose (C₆H₁₂O₆ and Oxygen(O2)

• Only Cellular Respiration

• Only Photosynthesis

• Both Cellular Respiration & Photosynthesis

Active transport requires ​ (a)   , moves materials from ​ (b)   , and goes ​ (c)   the concentration gradient.

• ATP
• HIGH TO LOW
• AGAINST
• Passive transport
• Low to high
• With the concentration gradient

Osmosis(passive transport) is the movement of

• salt

• sugar

• carbohydrates

• water

Both diffusion and facilitated diffusion are a type of passive transport since both don't require energy(ATP). What difference do they both have?

• Diffusion is passive and facilitated diffusion is active transport

• Diffusion does not require help from a protein while facilitated diffusion does

• Diffusion carries molecules through the semipermeable membrane from high to low concentrations, and facilitated is the opposite.
