Lesson 4 summary - Limiting factors

Image
- Whiteboard recap of key words relating to light dependent stage - Whiteboard recap of light independent stage including the terms "carbon fixation step" - Analysis of graphs showing the relative abundances of GP and TP in light and dark conditions: - GP increases because the conversion of GP to TP requires the products of the light dependent reactions - The carbon fixation step DOES NOT require these products and hence the levels of RuBP drop Photosynthetic pigments - Explanation of the need for additional photosynthetic pigments using the idea of red seaweed as an example Limiting Factors - Identification of temperature, light intensity and carbon dioxide concentration as the main limiting factors of photosynthesis MINI TEST TOPIC - Classification and Evolution

Control of blood glucose lesson

Image
- Recap of the structure and function of adrenal glands including location (above the kidneys), different regions and the functions of different regions - LEARN! - Recap of the role of hormones in negative feedback - every hormone is released from a specific gland and travels in the blood around the entire body. The hormone is detected by certain TARGET CELLS and an EFFECT is produced - Control of blood glucose is regulated by the hormones GLUCAGON and INSULIN - They are released from the ISLETS OF LANGERHANS in the pancreas - Glucagon is released when blood glucose levels fall. It effects the liver and results in an INCREASE in the concentration of blood glucose - Insulin is released when blood glucose levels rise. It effects the liver and results in a DECREASE in the concentration of blood glucose New associated key words:  GLUCONEOGENESIS: Production of new glucose in the liver and muscle cells from lipid molecules. Stimulated by GLUCAGON GLYCOGEN...
