But because such production depends on irrigation (which invites salt), heavy machinery (which compacts soil), and chemical fertilizers and pesticides made from petroleum products, the long-term ecological consequences have been devastating. Perennials tend to take longer to produce a food yield than the quick-growing annuals so heavily exploited by traditional agriculture, but they last longer and do better in marginal soils

In cellular respiration electrons travel from organic molecules to oxygen, while in photosynthesis electrons travel from oxygen in water to a carbon-based molecule. Throughout various steps in glycolysis and the Krebs cycle electrons are transported along a specific chain of molecules, known as the electron transport chain

Calvin cycle Synthesis portion of photosynthesis that takes place in the stroma of chloroplasts and does not directly require solar energy; it uses the products of the light dependant reactions to reduce carbon dioxide to a carbohydrate Part B Answer the following questions 1

A positively charged hydrogen atom (H+) has lost its only electron and is an ion, meaning that its one proton in its nucleus gives it a positive charge of +1. There is evidence that, millions of years ago, the ancestors of mitochondria and chloroplasts, two organelles ("mini organs") were actually prokaryotic organisms that entered into endosymbiotic relationships with eukaryotic cells

There are two reasons why energy from the oxidation of glucose is not used directly to drive chemical reactions in the cell: the hydrolysis of ATP releases small amounts of energy compared to the oxidation of glucose, and in a controlled way energy is released instantaneously from the hydrolysis of ATP, but the oxidation of glucose takes time Oxidation and reduction The types of chemical reactions called oxidation and reduction lie at the heart of respiration. This reaction requires phosphoric acid and energy gained from the reduction of NAD+ (oxidised form of nicotinamide adenine dinucleotide) to NADH (reduced form of nicotinamide adenine dinucleotide)

The accessory pigments capture wavelengths of light that chlorophylls cannot, and then transfer the energy to chlorophyll, which uses this energy to carry out the light reactions. The Photosynthetic ProcessThe initial process in photosynthesis is the decomposition of water (H2O) into oxygen, which is released, and hydrogen; direct light is required for this process

Living systems cannot directly utilize light energy, but can, through a complicated series of reactions, convert it into C-C bond energy that can be released by glycolysis and other metabolic processes. Chlorophyll - click on image to open All chlorophylls have: a lipid-soluble hydrocarbon tail (C20H39 -) a flat hydrophilic head with a magnesium ion at its centre; different chlorophylls have different side-groups on the head The tail and head are linked by an ester bond
