Respiration Flashcards
sucrose
glucose + fructose
Can you transport glucose in a plant
no
phloem moves from _____ to ____
source to sink
source
storage organ or photosynthetic leaf
sink
area that imports sugars to support metabolism
photoassimilates
sugars
does the transport of phloem sap occur actively
no passively- no energy
when there are lots of sugars pumped into a cell water potential (increases or decreases) and it becomes more (positive or negative)
water potential decreases and cell becomes more negative
once sugars are unloaded at the sink they can be 2 things
stored
broken down for energy and carbon skeletons
aerobic respiration
respiration that needs oxygen. the controlled release of energy via oxidation of sugar
inputs of respiration
glucose and o2
outputs of respiration
water energy and CO2
what is energy stored as
atp
where does respiration occur
all living parts of the plant- in mitochondira
where does glycolysis occur
cytoplasm outside of mitochondria
where does krebs and electron transport chain occur
in mitochondira
input of glycolysis
glucose
outcome of glycolysis
pyruvic acid and a little bit of ATP and NADH. You make 4 but use up 2 ATP
another name for the krebs cycle is
the citric acid cycle
what breaks down to form carbon dioxide
glucose
name the 3 steps of respiration
- glycolysis
- krebs
- electron transport chain
electron transport chain creates gradient of what
protons
where does water come from in respiration
the electron from NADH to attach to O2 = H2O
what is the total net yield of ATP
36 ATP
if 6 carbon go into respiration, do 6 come out
no- plant needs to grow and it uses carbon for this
respiration not only creates energy but helps support
maintenance, growth , nutrient uptake
