reactions: the light reactions and the Calvin cycle. Chlorophyll and the other molecules responsible for the light reactions are built into the thylakoid membranes. The enzymes that catalyze the Calvin cycle are located in the stroma. Beginning with the absorption of light by chlorophyll‚ the light reactions convert light energy into chemical energy in the form of ATP and NADPH. The ATP provides the energy‚ and the NADPH supplies the electrons for the Calvin cycle‚ which converts carbon dioxide to sugar

pantothenic acid. During the transitional between glycolysis and the Krebs cycle‚ pyruvic acid begins to prepare for entry into the cycle. The enzyme pyruvate dehydrogenase‚ changes pyruvic acid to a 2-carbon fragment called an acetyl group by removing a carbon dioxide molecule. Decarboxylation is the substance that causes the loss of a carbon dioxide molecule. In cellular respiration this is the first action that releases CO2. Pyruvic acid is also oxidized during this reaction. Krebs cycle

Brand Life Cycle The three phases through which brands pass as they are introduced‚ grow‚ and then decline. The three stages of the brand life cycle are the introductory period‚ during which the brand is developed and is introduced to the market; the growth period‚ when the brand faces competition from other products of a similar nature; and‚ finally‚ the maturity period‚ in which the brand either extends to other products or its image is constantly updated.

As all the students flooded into the classroom and started to unpack‚ the teacher‚ Mrs.Bentley‚ said‚ "Today you are going on a mini field trip to a park with Mrs.Crystal‚ who studies rocks and minerals! What you’re about to learn is a surprise!" The students cheered‚ wondering why they were going there. They gladly followed Mrs.Crystal out of the room and to the park nearby. Mrs. Crystal asked‚ "Do you know what inside a volcano?" Many hands shot up. She pointed to a girl. "Magma‚ and when it spews

OXYGEN-CARBON CYCLE The carbon-oxygen cycles are actually two independent cycles. However‚ both these cycles are interconnected as well as interdependent on each other to some extent. There are four processes involved in the completion of the carbon-oxygen cycle. Oxygen-carbon cycle processes are: * Photosynthesis Plants undergo photosynthesis that helps them produce energy and food for themselves. During photosynthesis‚ plants take in carbon dioxide (CO2) and absorb water (H2O) with the help
