The action spectrum of photosynthesis does not match exactly the absorption spectrum of any one photosynthetic pigment, including chlorophyll a. Each year, photosynthesis synthesizes billion metric tons of carbohydrate. Starch is stored in chloroplasts and in storage cells in roots, tubers, seeds, and fruits. The following set of questions deals with linear electron flow: a. The stomata are not only the major route for gas exchange CO2 in and O2 outbut also for the evaporative loss of water. The key enzyme, phosphoenolpyruvate carboxylase, adds CO2 to phosphoenolpyruvate PEP to form oxaloacetate. Rubisco is the most abundant protein in chloroplasts and probably the most abundant protein on Earth.

Heterotrophs live on organic compounds produced by other organisms. Photosynthesis is two processes, each with multiple stages. Upload document Create flashcards. As a review, define the terms autotroph and heterotroph. Almost all heterotrophs are completely dependent on photoautotrophs for food and for oxygen, a by-product of photosynthesis.
Water is split in the process, and O2 is released as a by-product. Explain what occurs in the light reactions stage of photosynthesis.

|Plants also store excess sugar by synthesis of starch.
A photosystem is composed of a reaction center surrounded by a light-harvesting complex. In a complex series of reactions, the carbon skeletons of five molecules of G3P are rearranged by the last steps of the Calvin cycle into three molecules of RuBP. In phase two, the reduction stage, what molecule will donate electrons, and so is the source of the reducing power? If the 18O was introduced to the plant in the form of CO2, the label did not turn up in the released O2.

So, the question has a mistake—but the response should be either to note this error, and explain what is meant by P, or note the error and explain that P molecules form the reaction center for photosystem II. Sugar made in the chloroplasts supplies the entire plant with chemical energy and carbon skeletons to synthesize all the major organic molecules of cells.
Use two key differences to explain how chemiosmosis is different in photosynthesis and cellular respiration.

In other words, mitochondria use chemiosmosis to transfer chemical energy from food molecules to ATP, whereas chloroplasts transform light energy into chemical energy in ATP. An enzyme extracts electrons from water and supplies them to the oxidized reaction center.
See page of your text for the labeled figure. The only photons that a molecule can absorb are those whose energy matches exactly the energy difference between the ground state and excited state of this electron.

|The enzyme that catalyzes this first step is RuBP carboxylase, or rubisco.
The cycle begins by incorporating CO2 from the air into organic molecules already present in the chloroplast.

A unique leaf anatomy is correlated with the mechanism of C4 photosynthesis. Light is a form of energy known as electromagnetic energy, also called electromagnetic radiation. Located centrally in a photosystem, this complex triggers the light reactions of photosynthesis.
