Photosynthesis ๐ฟ and Cellular Respiration ๐ฅ
(Chp9&10)
,
๐๏ธ WHERE IT HAPPENS + WHOโS RUNNINโ IT
๐ฟ Chloroplasts โ the solar panels of the cell
โ๏ธ catch light โ flip it into sugar
๐งฉ thylakoids = lil discs where the light show happens
๐ง stroma = open space where sugarโs actually made
๐ฅ Mitochondria โ the engine room
๐ takes that sugar โ turns it into power (ATP)
๐ cristae = those folds where energy gets extracted
๐ฅฃ matrix = chemical soup for the cycle stuff
โก Same universal plug:
ATP synthase = the outlet everything charges from
electrons flow, Hโบ spins it like a windmill โ boom, ATP made
๐ Energy couriers:
๐ฟ NADPโบ โ NADPH (plant version)
๐ฅ NADโบ โ NADH / FAD โ FADHโ (cell version)
they just carry the spark from one reaction to another
.
๐ HOW THE ENERGY FLOWS
โ๏ธ Sunlight hits โ chlorophyll wakes up ๐ฟ
โก light reactions go crazy โ split water, drop Oโ like confetti
โ make ATP + NADPH = โplant batteries chargedโ ๐
๐ฌ Calvin Cycle slides in (in the stroma)
โ grabs COโ from the air ๐ซ๏ธ
โ uses those charged-up ATP/NADPH packs to build sugar
๐ญ basically turns air and light into food
๐ฅ Then mitochondria clock in
โ break that same sugar down (cellular respiration)
โ take glucose + Oโ โ drop COโ + HโO
โ ATP floods out ๐ฅ โ energy we actually use
๐ Whole thing loops:
plants breathe out Oโ โ we breathe it in
we breathe out COโ โ plants breathe it in
โ๏ธ everything feeding everything
.
โ๏ธ STAGES INSIDE THE LOOP
๐ฟ PHOTOSYNTHESIS SIDE
1๏ธโฃ Light Reactions โ charge up
โ๏ธ light hits pigments โ water splits
๐จ Oโ leaves, Hโบ builds a gradient
๐ ATP synthase spins โ ATP made
๐ NADPH formed โ both carry juice to the next step
2๏ธโฃ Calvin Cycle โ cash out that energy
๐ซ๏ธ grabs COโ + uses ATP/NADPH
โ builds G3P โ becomes glucose ๐ฌ
๐ง think: plantโs โVenmo transferโ of stored sunlight
โธป
๐ฅ CELLULAR RESPIRATION SIDE
1๏ธโฃ Glycolysis โ first chop
๐ glucose โ 2 pyruvates + lil ATP
๐ญ no Oโ needed โ quick cash grab
2๏ธโฃ Pyruvate Oxidation โ entry fee to the mitochondria
โ pyruvate trimmed into Acetyl-CoA + COโ
3๏ธโฃ Krebs Cycle โ spin cycle
โป๏ธ burns Acetyl-CoA โ releases COโ
โ makes NADH + FADHโ + lil ATP
4๏ธโฃ Electron Transport Chain โ final payout
โก NADH/FADHโ dump electrons โ Oโ waits at the end
๐ Hโบ pumped, ATP synthase spins โ big ATP bag ๐ฐ
๐ง Oโ grabs electrons โ forms HโO
๐ THE LOOP OF LIFE (BIG PICTURE)
โ๏ธ Sunlight = the source ๐
๐ฟ Plants grab it โ stash it as glucose
๐ฅ We take that glucose โ turn it into ATP
๐จ Plants drop Oโ โ we breathe it in
๐ญ We drop COโ โ they breathe it in
Thatโs the energy handshake ๐ค between plants and animals
๐งฉ Photosynthesis builds it up (Anabolic)
๐๏ธ stores energy โ makes glucose
Respiration breaks it down (Catabolic)
๐ฅ releases energy โ makes ATP
โก ATP = the real currency
๐ธ glucose is the savings account
๐ฅ ATP is the cash you actually spend
๐ง Nothingโs wasted โ just transferred.
Sunlight becomes motion, thought, growth, life.
๐ ATP synthase is the middleman โ works in both systems
โ same tech, different factory
โ one powered by light, one by sugar
