The calvin cycle

The process of photorespirationalso known as C2 cycle, is also coupled to the dark reactions, as it results from an alternative reaction of the RuBisCO enzyme, and its final byproduct is also another glyceraldehydeP. Overview of the Calvin cycle and carbon fixation The Calvin cycle, Calvin—Benson—Bassham CBB cycle, reductive pentose phosphate cycle or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms.

Note that some books list five stages in the sleep cycle. These books consider the first five to ten minutes when you are falling asleep as a stage in The calvin cycle sleep cycle.

We think this is more of a transitional phase and not really part of the cycle, especially since this stage of sleep does not repeat itself, while the other four stages do repeat themselves throughout the night.

The sleep cycle repeats itself about an average of four to five times per night, but may repeat as many as seven times. Thus, you can see how a person has several different dreams in one night. The Stages Of Sleep The stages in the sleep cycle are organized by the changes in specific brain activity.

You are entering into light sleep. This stage is characterized by Non-rapid eye movements NREMmuscle relaxation, lowered body temperature and slowed heart rate.

The body is preparing to enter into deep sleep. Also characterized by NREM, this stage is characterized by a further drop in body temperature and relaxation of the muscles. The endocrine glands secrete growth hormones, while blood is sent to the muscles to be reconditioned.

In this stage, you are completely asleep. Still in the NREM stage, this is an even deeper sleep. Your metabolic levels are extremely slow.

In this stage of sleep, your eyes move back and forth erratically as if watching something from underneath your eyelids. Referred to as REM sleep or delta sleep, this stage occurs at about minutes after the onset of sleep.

Your blood pressure rises, heart rate speeds up, respiration becomes erratic and brain activity increases. Your involuntary muscles also become paralyzed or immobilized.

This stage is the most restorative part of sleep. Your mind is being revitalized and emotions is being fine tuned. The majority of your dreaming occurs in this stage.

If you are awakened during this stage of sleep, you are more likely to remember your dreams. These stages repeat themselves throughout the night as you sleep. As the cycle repeats, you will spend less time in stages 1 to 3 and more time dreaming in stage 4.

In other words, it will be quicker and quicker for you to get to stage 4 each time the cycle repeats.BioCoach Activity Concept 8: Cooperation of the Light Reactions and the Calvin Cycle.

Photosynthesis depends on an interaction between two sets of reactions: the light reactions and the Calvin cycle. Friday, December 10, The Calvin cycle is a set of light independent redox reactions that occur during photosynthesis and carbon fixation to convert carbon dioxide into the sugar glucose.

The calvin cycle

These reactions occur in the stroma of the chloroplast, which is the fluid-filled region between the thylakoid membrane and inner membrane of . In the most general sense, the primary function of the Calvin cycle is to make organic products plants need, using the products from the Light Reactions of photosynthesis (ATP and NADPH), These products include glucose, the sugar made using carbon dioxide and water, and also protein (using nitrogen fixed from the soil) and lipids (e.g., fats and.
