Biology 150 EXAM III Graded A Where do light reactions occur? thylakoid Where do dark reactions occur? stroma Brainpower Read More What are the two components of the light reaction? 1. Light Capture 2. Energy Harvest What is Light capture? Light interacts with chlorophyll. When an electron absorbs a photon, it is excited. When an electron emits a photon it relaxes back to ground state. What is the structure of a photosystem? -Chlorophyll a molecules -Primary electron ac...

What is a metabolic pathway? - Answer-A pathway that a molecule goes through, resulting in a specific product. What is metabolism? - Answer-The totality of an organisms chemical reactions Gibbs free energy - Answer-Portion of a system that can perform work when temp and pressure are uniform throughout the system. What does a negative Delta G mean? - Answer-A process that is spontaneous/exergonic What does spontaneous mean? - Answer-Means that a process will occur. What happens to the ener...

Skill: Application/Analysis Campbell's Biology, 9e (Reece et al.) Chapter 10 Photosynthesis Students find this chapter quite challenging. Fortunately, some of the key concepts, such as chemiosmosis and redox, were discussed previously in the chapter on respiration and fermentation. The new key concepts are light as energy, light absorption and energy conversion by pigments, and linear and cyclic electron flow. Students are challenged to identify the relationships between the light reac...
