WebMar 28, 2024 · Stroma commonly refers to the fluid filled inner space of chloroplasts surrounding thylakoids and grana. Initially, the stroma was thought to simply provide support for the pigmented thylakoids. WebThe unusually dense stroma of pancreatic cancers is thought to play an important role in their biological aggression. The presence of hypoxia is also considered an adverse prognostic factor. Although it is usually assumed that this is the result of effects of hypoxia on the epithelial component, it is possible that hypoxia exerts indirect effects via the …

WebAug 25, 2024 · What is the pH difference between the thylakoid space and the stroma? During photosynthesis, the lumen becomes acidic, as low as pH 4, compared to pH 8 in the stroma. This represents a 10,000 fold concentration gradient for protons across the thylakoid membrane. WebStromal pH after either 20 or 90 min of eye closure was 7.39 +/- 0.01 (n = 12, +/- SEM) and returned to 7.54 within 10-15 min of opening the eye, t1/2 = 3 min. Eye closure was simulated by exposing the eye to a gas mixture of 7.1% O2, 6.7% CO2, balance N2, which was passed through tight-fitting goggles. how does insulin process blood sugar
