Share buttons are a little bit lower. Published by Merryl Phillips Modified over 3 years ago. Life on Earth Audesirk Chapter 9 Biology: Life on Earth Audesirk Photosynthesis Chapter 7.

Chapter 7 What Is Photosynthesis? Photosynthesis is the ability to capture sunlight energy and convert it to chemical energy Most forms of life on Earth depend on the chemical energy produced by photosynthetic organisms.

Life on Earth Audesirk Interconnections: Both processes create ATP…remember…the energy molecule from chapter 6?? Life on Earth Audesirk Structures of Photosynthesis Chapter auresirk Use for zoomed out locations of each structure…details follow next… Chapter 7. Contains the enzymes needed for the auedsirk of photosynthesis. Location of light independent reactions of photosynthesis.

Disk-shaped sacs called thylakoids found within the stroma in stacks called grana. Chlorophyll found in thylakoids. Chapter 7 End of Photosynthesis Lecture 2 Quiz tomorrow!!!!!

The light energy captured by photosynthesis is temporarily stored within these two compounds. Light travels in waves A wavelength is the distance from one wave peak audesjrk the next The different colors of light correspond to different regions of the visible spectrum and are identified by their wavelengths. Violet light has the shortest wavelength and red light has the longest. Electron returns to original state and energy is lost as heat OR The excited electron leaves the atom and is accepted by the electron acceptor molecule.

Light we see Transmission of certain wavelengths aaudesirk passes through. Chlorophyll a and chaptter absorbs light in the blue and red regions. Green NOT absorbed Accessory pigments such as carotenoids- yellow and orange. Green sometimes yellow, orange, red …plants reject wudesirk reflect that light back to our eyes Carotenoids Phycocyanin Wavelength nanometers Chapter 7.

Chlorophyll is used in photosynthesis and gives leaves their green color.

Audesirk – 7 Chapter 7 Capturing Solar Energy: Photosynthesis I

As the days shorten, trees stop producing chlorophyll, allowing other pigments to take over. Oxygen is released Dark reactions actually make the sugar in the final step.

Both energize electrons using sunlight. The green areas are chlorophyll molecules ETC are a series of enzymes that pass the electrons down Chapter 7.

Audesirk – 7 Chapter 7 Capturing Solar Energy: Photosynthesis I

The ETC is a series of proteins embedded in the thylakoid membrane. Energy will be used in the light independent reactions. Oxygen is released into the air. Chapter 7 Why is the calvin cycle in plants directly and indirectly important to animals? Carbon fixation carbon capture Carbon atom from carbon dioxide bonds with a five carbon sugar called ribulose biphosphate RuBP to form an unstable 6 carbon sugar.

This requires three more ATP.

This replenishes the RuBP that was used up, and the cycle can continue. The 6th molecule of PGAL is available to the audesir to make sugar.

In the end, the six carbons from the CO2 can be accounted for by the harvest of a six carbon molecule. Substantial leaf porosity leads to substantial water evaporation, causing dehydration stress on the plant Plants evolved waterproof coating and adjustable pores stomata for CO2 entry.

O2 is used up as CO2 is generated No useful cellular energy made No glucose produced Photorespiration is unproductive and wasteful.

Much photorespiration occurs under hot, dry conditions Chapter 7. Oxalo travels to bundle sheath cells, breaks down to release CO2, regular C3 can take place Cnapter plants use more energy to create glucose C4 thrive in deserts, and midsummer much light, little water Almost no photorespiration occurs under hot, dry conditions.

Much glucose synthesis occurs.
