Light Dependent Reactions 2 Flashcards
What is a coenzyme
Coenzyme is a non protein compound essential to enzyme function.
What is photosynthesis
Photosynthesis is using energy from sunlight to convert water and C02 into organic molecules e.f glucose with release of 02
What are LDR affected by
LDR are affected by temperature
How are grana/lamellae adapted for photosynthesis
Grana/lamellae are adapted for photosynthesis by:
Large surface area of attachment of enzymes
Numerous membranes are available for attachment of pigment molecules (which absorb light energy) to chlorophyll
How is Hydrogen stored in carbs
Hydrogen is stored in carbs when hydrogen reacts with C02 to store H.
Why can excited electrons easily move from protein to protein
Excited electrons can easily move fro protein to protein because the electron carriers are located in the thylakoid membranes in chloroplast and the positioning of thylakoid membranes create an electron transport chain
What is role of NAPD I LDR
Role of NAPD in LDR
Carry hydrogen to LIR
Act as hydrogen carrier
So 0xygen and hydrogen don’t react
Where are PSI AND PSII chlorophyll found
PSI and PSII chlorophyll are found in thylakoid membranes of chloroplast, each is a central chlorophyll within a photosynthesis.
What is a photo system
A photosystem is a complex in membrane which has chlorophyll
What are products of LDR
products of LDR are
Reduced NADP H
02 (waste products)
ATP
What is light energy used for
Light energy is used for
Phosphorylation
Reduce NAPD to form reduced NAPD
Photolysis ,splitting water into protons (H+), electrons and 02
