Calvin cycle reactions - enzymatic reactions that reduce carbon dioxide to a carbohydrate in the stroma of chloroplasts ATP synthase - protein structure in chloroplast thylakoids and mitochondria cristae that uses energy from H+ ions to convert ADP to ATP autotrophs - organisms that produce their own food C3 plants - the most common and the most efficient at photosynthesis in cool, wet climates C4 plants - plant that has adapted its photosynthetic process to more efficiently handle hot and...

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...

AQA A-level BIOLOGY (7402/1) Paper 1 MARKING SCHEME QUESTIONS AND ANSWERS 2024 SPECIMEN VI Question 1: (a) Describe what is meant by the term 'metabolic rate'. [2] (b) Explain how the control of body temperature is an example of homeostasis. [4] Answer 1: (a) 'Metabolic rate' refers to the rate at which chemical reactions occur within an organism's cells. It's a measure of the amount of energy expended by an organism per unit of time. (b) The control of body temperature is ...

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...

Muscle movement on the cellular level is initiated by the release of Ca2+ from the terminal cisternae. Terminal cisternae are associated with A. sarcoplasmic reticulum. B. myosin cross-bridges. C. myoglobin. D. canaliculi. E. thin filaments. - Answer-A Muscle fibers store Ca++ in the sarcoplasmic reticulum for release during contraction. The sarcoplasmic reticulum, analogous to the endoplasmic reticulum, runs extensively throughout the fiber so that released Ca++ will come into imm...
