Glycolysis Worksheet ? Answer Sheet 1. Explain why the phosphate end of ATP stores potential energy. Each of the phosphate groups is negatively charged. These negative repel each other and so they would have less energy if they were further apart. 2. Which has more potential energy, ATP or ADP? ATP has more potential energy than ADP since it has three negatively charged phosphates held together vs only two in ADP. 3. Write the overall reaction for cellular respiration. Glucose + 6 O2 6 CO2 + 6 H2O (+ energy in the form of ATP and heat) 4. What atom is known as an ?electron grabber? because it attracts electrons so strongly? oxygen 5. What is an electron transport chain?

14.1 Structure of ribonucleic acid The genetic code Sequence of nucleotides in DNA forms a code that determines the sequence of amino acids in the proteins. In eukaryotes the DNA code is largely confined to the nucleus. The synthesis of proteins takes place in the cytoplasm. Sections of the DNA code are transcribed onto a single-stranded molecule called ribonucleic acid RNA. There are a number of types of RNA. The one that transfers the DNA code from the nucleus to the cytoplasm acts as a type of messenger and is called messenger RNA (mRNA). This mRNA is small enough to leave the nucleus through the nuclear pores and to enter the cytoplasm, where the code that it contains is used to determine the sequence of amino acids in the proteins which are synthesised there.

7.1 Succession Ecological succession is the directional change in the composition of species that occupy a given area through time: it involves initial colonization and establishment of pioneer plant species, followed by their replacement with other species until a relatively stable community is formed. Ecosystems are made up of all the interacting biotic (food availability, competition and predation)and abiotic (non-biological environment ? pH, temperature, rainfall and humidity)factors in a particular area within which there are a number of communities of organisms. Ecosystems constantly change, Succession is the term used to describe these changes, over time, in the species that occupy a particular area. A sere (seral stage) is the series of stages in succession.

Chapter 9: Cellular Respiration, Harvesting Chemical Energy The principles of energy harvest Cellular respiration and fermentation are catabolic energy yielding pathways Cells recycle ATP they use for work Redox reactions release energy when electrons move closer to electronegative atoms Electrons ?fall? from organic molecules to oxygen during cellular respiration The ?fall? is stepwise during respiration via NAD+ and an electron transport chain The process of cellular respiration Respiration involves glycolysis, Krebs cycle and electron transport Glycolysis harvests chemical energy by oxidizing glucose to pyruvate The Krebs cycle completes the energy yielding oxidation of organic molecules
