Chloroplasts are adapted for the light-independent reaction by the stroma fluid containing necessary enzymes, the ability to maintain a chemical environment with high enzyme and substrate concentration, and the presence of DNA and ribosomes for protein synthesis.
Cloroplastele sunt adaptate pentru reacția independentă de lumină prin fluidul stromei care conține enzimele necesare, capacitatea de a menține un mediu chimic cu concentrație ridicată de enzime și substraturi, și prezența ADN și ribozomilor pentru sinteza proteinelor.
| Front | How are chloroplast adapted to carrying out the light independent reaction of photosynthesis |
|---|---|
| Back | Fluid of stroma contains all the enzymes required to carry out the light independent reaction. Stromal fluid is membrane bound in chloroplast which means a chemical environment which has high concentration of enzymes and substrates can be maintained. Stroma fluid surrounds grana and so the products of light-dependent reaction in the grana can readily diffuse into the stroma It contains both DNA and ribosomes so it can quickly and easily manufacture some of the proteins involved in the light-dependent reaction. |
