LECTURE 36 ANNOUNCEMENTS 1. QUIZ 9: A 23.1 B 22.9 C 24.0 WEDNESDAY’S LECTURE TODAY WHAT HAPPENS IN PLANT PHOTOSYNTHESIS BIOSYNTHESIS OF FATTY ACIDS SO-CALLED "FUTILE CYCLE" aka "SUBSTRATE CYCLE" GLUCONEOGENESIS EVENTS IN PSII . RAPID TRANSFER OF e - FROM P680*, EVENTUALLY TO MOBILE QUINONE . BUILD-UP OF POSITIVE CHARGE IN THE OEC, THEN OX. OF 2H 2 O . 4H + PUMPED FROM STROMA INTO LUMEN FOR EACH O 2 EVOLVED AT CYT-bf (SIMILAR TO COMPLEX III IN MITOCHONDRIA) . Q-CYCLE OCCURS, WITH H + PUMPING; WATER-SOL. REDUCED PROTEIN PRODUCT, PLASTOCYANIN 2. HOW TO STUDY THIS MASS OF FACTS RE OX PHOS AND PHOTOSYNTHESIS?! USE LAST YEAR'S QUIZZES AS A GUIDE MY OVERALL PLAN IS TO SHOW SOME STEP(S) AND ASK "WHAT HAPPENS?" OR TO ASK, "AT WHICH STEP DOES XXX HAPPEN?" AT PSI, e - FROM PLASTOCYANIN USED TO FORM NADPH 3. TODAY AT 2:55PM IN COMSTOCK B108: MED SCHOOL INTERVIEW EXPERIENCES H + GRADIENTS FROM PSII AND CYT-bf USED IN CHLOROPLAST TO SYNTHESIZE ATP

ANABOLISM METABOLISM UNTIL NOW: BIOENERGETICS -- HOW SUGARS, FATS, AND AA ARE OXIDIZED TO PRODUCE ATP; HOW ENERGY IN SUNLIGHT ATP AND NADPH BIOSYNTHETIC PATHWAYS THAT WE WILL STUDY: START: GLUCONEOGENESIS, “NEW GLUCOSE FORMATION” FROM NON- SUGAR PRECURSORS BRAIN AND NERVES USE 3/4 OF BODY’S GLUCOSE. THEY PERFORM MUCH GLUCONEOGENESIS (BUT NO FAT SYN! THEY STORE ALMOST NO FAT) ENOUGH GLUCOSE STORED AS GLYCOGEN FOR ~1 DAY’S NEEDS BODY MUST CONTINUOUSLY SYNTHESIZE GLUCOSE. NOT INTERCONVERSION OF SUGARS FACTS ABOUT USE OF GLUCOSE AS FUEL : RED BLOOD CELLS ALSO STORE NO FAT USE GLUCOSE. SKELETAL MUSCLE CELLS DO STORE FAT, AND USE GLUCOSE. 90% OF GLUCONEOGENESIS OCCURS IN LIVER.
