Introduction to Climate Change The term climate refers to the weather conditions in a region over a long period of time i.e. several decades When the weather conditions in a region change significa...
Practical: The Hill Reaction The light-dependent reactions of photosynthesis take place in the thylakoid membrane and involve the release of high-energy electrons from chlorophyll molecules in phot...
Products of Photosynthesis Intermediate molecules of the Calvin cycle such as glycerate 3-phosphate (GP) and glyceraldehyde 3-phosphate (GALP) are used to produce other biological molecules needed ...
Light-independent Reactions The light-independent reactions of photosynthesis are sometimes referred to as the Calvin cycle The reactions produce complex organic molecules such as Starch for storag...
Light-dependent Reactions Photosynthesis takes place in two distinct stages The light-dependent reactions, which rely on light directly The light-independent reactions, which do not use light direc...
Chloroplasts: Structure & Function Chloroplasts are the organelles in plant cells where photosynthesis occurs Each chloroplast is surrounded by a double-membrane known as the chloroplast envelo...
ATP as a Supply of Energy All organisms require a constant supply of energy to maintain their cells and stay alive This energy is required e.g. For building new molecules from the products of diges...
Photosynthesis: An Overview Photosynthesis is a series of chemical reactions that occurs in producers such as plants and algae Photosynthesis converts light energy into chemical energy which is the...
Calculating the Efficiency of Biomass & Energy Transfers Transfer of energy through a food chain During photosynthesis organisms such as plants convert light energy into chemical energy stored ...
