Cellular Energy Flashcards
(49 cards)
what is considered anabolic and why
photosynthesis bc it forms glucose molecules
cellular respiration and photosynthesis are considered to be a metabolic pathway, this must mean
glucose is the substrate for cellular respiration
when the bond between the 2nd and 3rd phosphate group of a molecule of ATP is broken
energy is released and the 3rd phosphate is free
why is ATP considered to be one of the most important biological molecules
ATP provides energy
the law of conservation of energy states that when one form of energy is converted into another,
no energy is created nor destroyed
example of catabolic pathway
releasing energy while breaking down large molecules such as glucose
according to the laws of thermodynamics
energy cannot be converted without the use of useable energy
the molecules produced during photosynthesis store energy within their bonds, the energy,
originated from the sun, and will be released when glucose is broken down
what is the main purpose of the calvin cycle
sugar production
the transferring of chemical energy to the 3 PGA molecules is transferred through
ATP and NADPH molecules
where does the light-independent phase of photosynthesis take place
stroma
what gas enters the stroma to start the calvin cycle
carbon dioxide
this enzyme is able to convert inorganic carbon dioxide into organic molecules
Rubisco
what happens to the two G3P molecules that leave the calvin cycle
they are used to make glucose, fructose, starch and other organic molecules
carbon fixation
the joining of carbon with other organic molecules
what are the products of photosynthesis
oxygen and sugars
the energy acquired in the light dependent reactions is used in the light independent reactions to build glucose molecules. How is this energy transferred from light dependent to light independent reactions
in the bonds of ATP and NADPH molecules
summary of chemiosmosis
hydrogen atoms move down their concentration gradient out of the thylakoid into the storm through ion channels in the membrane
what captures energy from sunlight during photosynthesis
chlorophyll and other pigments
the final receptor that transfers electrons to NADP+ is a protein called
ferrodoxin
where do the light dependent reactions take place during photosynthesis
thylakoids
infer why chloroplasts are found mostly in the leaves of plants
the large surface area provides for maximum light absorption
oxygen atoms released during phase 1 of photosynthesis originated
from splitting of water molecules
the stage of respiration that releases most of the energy in glucose occurs in the
mitochondria
