Oxygenic photosynthesis -found in cyanobacteria -uses H2O as proton donor -Produces O2 -2 photosystems -linear flow of electrons -uses Calvin cycle -uses Chl a Anoxygenic photosynthesis -uses H2S as proton donor -produces S -green sulphur bacteria use reverse cycle to incorporate CO2 rather than produce it -green non-sulphur bacteria use the hydroxypropionate pathway (ancestral pathway) Photosystem I -similar to Chlorobi (Green S. bacteria) and Firmicutes (Heliobacterium) -has ferrodoxin Phot...

What happens when a suitable substrate binds to an enzyme? - ANSWER-The active site amino acids bond with the substrate Cyanide binds to cytochrome oxidase at a site where the substrate oxygen would normally bind. This is an example of - ANSWER-competitive inhibition an example of a catabolic reaction is - ANSWER-lactate fermentation what is an anabolic process that is endergonic and endothermic? - ANSWER-CH₄ +2O₂ → CO₂ + 2H₂O ATP yields 7.3 kcal/mol of free energy and it i...

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...

AQA A-Level Biology. 3.2 – Cells All Answers Correct Structure of Nucleus. 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RN...
