ADAPTIONS

• ADAPTIONS OF THE CHLOROPLAST FOR THE LIR?

  • stroma fluid contains enzymes for LIR
  • stroma fluid surrounds grana
  • chloroplast contains DNA and ribosomes
• REASON FOR STROMA FLUID CONTAINING ENZYMES?

  • is membrane-bound
  • maintains high concentration of enzymes and substrates
• WHY DOES THE STROMA FLUID SURROUND THE GRANA?

  allows products of LDR to readily diffuse into stroma
• WHY DOES THE CHLOROPLAST CONTAIN BOTH DNA AND RIBOSOMES?

  can quickly manufacture proteins involved in the LIR
