Biology Study Guides - SparkNotes Cellular Respiration I. Reaction: C6H12O6 + 6O2 + 6H2O ——> 6CO2 + 12 H2O + energy (38 ATP and heat) II. Aerobic Cellular Respiration occurs in three stages. A. Glycolysis (occurs in the cytoplasm) 1. One glucose is split into two pyruvates (C3H4O3). 2. 4 ATP are produced‚ but 2 endergonic reactions use up 2 ATP. 3. Glycolysis requires no oxygen‚ and occurs whether oxygen is present or not. 4

Section 9-1 Review Key Ideas 1. Identify the primary source of energy that flows through most living systems The sunlight. Autotrophs use sunlight to make their own food. Organisms that can’t make their own food consumed the food molecules made by autotrophs‚ eat autotrophs or eat organisms that consumed autotrophs. 2. Explain how an organism’s metabolism is related to Earth’s carbon cycle. An organism’s metabolism is related to using energy to build organic molecules which contain

process of the breakdown of nutrients (glucose) to release energy. It occurs in cells of the organism It is of 2 types- Anaerobic (No Oxygen) and Aerobic (Oxygen) Glucose + Oxygen Carbon Dioxide + Water + Energy C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy (34-36 ATP + heat) Movement Movement is the change of position of an organism to change positions or move pats of them. Plants too move in various different ways. The movement may be so slow that it is very difficult

The first lab will investigate the movement of glucose and starch across a selectively permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors

photosynthesis are sunlight‚ carbon dioxide‚ and water. Sunlight begins the reaction‚ then water molecules are split to form energy-containing compounds and finally‚ the carbon dioxide is fixed to form glucose. The equation for photosynthesis is C6H12O6 + 6O2-------> 6CO2 + 6H2O +ATP. The photosynthesis process contains two phases‚ the light and dark reactions. During both phases‚

or the accumulation of product. Photosynthesis consists of light reactions and dark reactions. This process can be simplified by the equation: 6CO2 + 6H2O + Energy --> C6H12O6 + 6O2 Shown in this equation 6 molecules of carbon dioxide (6CO2) and 12 molecules of water (12H2O) being consumed in the process‚ and glucose (C6H12O6)‚ six molecules of oxygen (6O2)‚ and six molecules of water (6H2O) being produced. The energy source is photons (light) from the sun. The rate of photosynthesis could be

Safety/Science Foundations 1. Avoid the situation; don’t touch 2. Close-toed shoes 3. Students 4. To protect your eyes from chemicals 5. Before starting the lab 6. Students should not play around and follow directions. Students should clean up after their selves after finishing a lab. 7. Hypothesis - a testable explanation for an observation 8. Observation - statement made using senses. ex. I hear chirping Inference - interpretation from observations. ex. "The chirping is from the bird"
