This unit on Alligators describes the characteristics of alligators, their size, features, what they eat and where they live. Their nesting habits and baby alligators are discussed. Activity worksheets include; word find, word unscramble, criss cross, spelling
A resource aimed at advanced biology students, this worksheet is a starter or plenary exercise that requires students to draw out a biochemical flow chart showing the sequence of events that occur during glycolysis. After this initial memory recap, students are then required to answer a series of questions about the process which checks that they understand the key points.
Key words: glycolysis, pyruvate, glucose, NAD, reduction, oxidation, coenzyme, ATP, energy, ADP, cytoplasm, anaerobic, triose phosphate
A resource aimed at advanced biology students, this is a practical activity worksheet that concisely describes the classic experiment involving methylene blue as an artificial hydrogen acceptor in respiration. The experiment involves setting up three test tubes (two with yeast and methylene blue, one without yeast as a control) and observing the decolouration of methylene blue as it is gradually reduced due to the respiratory activity of yeast. The activity sheet contains the technical details of solutions required, a table for students to record their observations and a series of questions that probe student's understanding of the biochemistry involved with these observations. Answers to the questions are provided on the second, duplicate, worksheet.
Key words: Respiration, glucose, NAD, methylene blue, reduction, oxidation, yeast, control
