Associate Program Material – Heather Earnhardt Cell Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the process by which electrons are transferred between glucose to coenzymes and then to oxygen. NTP is made by the relocation of electrons. The end result of the process is the carbon dioxide and water that are released as byproducts of the process. The three

Introduction The aim of this practical 1 is to determine the rate of photosynthesis by measuring the rate of oxygen production‚ which is a direct consequence of PSII activity. Results Graph 1 Graph 2 Discussion i. It took 2 minutes before any increase in the O2 concentration of the chamber was observed‚ it took 2minutes‚ after illuminating the leaf. ii. There are 2 main parts of the photosynthesis‚ light dependent part and light independent part‚ the O2 is released in last part which is light-independent

increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate of photosynthesis will also increase in a linear trend. Carbon dioxide concentration is shown to be directly proportional to rate of photosynthesis ([CO2] ∝ rate of photosynthesis). The line of best fit

so that it can be used by the organism. For example‚ when we looked at how plants get energy we say that plants’ main source of energy is sunlight. But‚ we noticed that light energy cannot be directly used by the plant. So‚ using the process of Photosynthesis plants can effectively turn light energy into “usable” or kinetic energy. This process consists of two sub-processes‚ light dependent and light independent. In a plant cell there is an organelle called the chloroplast. In each plant cell there

water and nutrients. * Each part of the plant has a specific function: * * leaves - carry out photosynthesis. * roots - anchor the plant & absorb water and soil nutrients. * stems - support the leaves and transport materials to other plant parts. * What does the plant use the glucose for? The plant uses sugars produced during photosynthesis to builts its structure. * Petiole - the stalk that attaches the leaf to the stem. * Covering the upper

Maldonado Abstract: In this lab the students did two labs in which they learned the process of photosynthesis‚ which involves the use of light energy to convert carbon dioxide and water into sugar‚ oxygen‚ and other organic compounds. Oxygen is released as a product. This process is often summarized by the following reaction: 6CO2 + 12H2O ------> C6H12O6 + 6H2O + 6O2 The energy of photosynthesis comes from absorbed photons found in light and involves a reducing agent‚ in this case water. The

Cellular respiration is the aerobic harvesting of energy from food molecules. The first stage of cellular respiration is Glycolysis. The second stage of cellular respiration is the citric acid cycle. Lastly‚ the third stage of cellular respiration is the electron transport. • What is the role of glycolysis? Include

Theodor Wilhelm Engelmann was a German microbiologist whose 1882 experiment measured the effects of different colors of light on photosynthetic activity and showed that the conversion of light energy to chemical energy took place in the chloroplast. In 1881‚ he observed the movement of bacteria towards the chloroplasts in a strand of “Spirogyra” algae. Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photo synthetically active chloroplasts in the algae.

Lil Dejay C4 2/10/14 Photosynthesis: Making Energy Chloroplasts Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis‚ and to store food energy. Chloroplasts contain the pigment‚ chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum‚ and reflects only green and yellow
