What occurs during the light reactions of photosynthesis?
Give this one a try later!
Through excitation of chlorophyll molecules, sunlight energy splits water
molecules into oxygen atoms and hydrogen ions, and electrons; oxygen is
released as a waste product; sunlight energy is transfer to the energy
carrier molecules ATP and NADPH through transfers of hydrogen ions and
electrons; no sugar is made in this phase of photosynthesis
What are the four processes of aerobic cellular respiration (remember Get That Cell
Energy)?
Give this one a try later!
, glycolysis, transition reaction, citric cycle, electron-transport chain
Can energy or mass be used up?
Give this one a try later!
No only transformed (changed) into different forms
What is the role of glucose in cellular respiration? Pyruvate? Acetyl CoA? NADH?
FADH2? oxygen? carbon dioxide? water?
Give this one a try later!
Glucose: convert into ATP which the cell then uses to carry out processes
and grow
Pyruvate: product of glycolysis (2); initial storage for glucose; most energy
into pyruvate
Acetyl CoA: stores energy from pyruvate; product of transport reactions
NADH AND FADH2: energy carriers
Oxygen: last electron recepter
Carbon dioxide: waste released into the mitochondria
Water: waste
What happens when an organism stops respiring?
Give this one a try later!
, It is dead
What is the meaning of the word "food" in the context of biology and photosynthesis?
Give this one a try later!
carbohydrates/polysaccharides=starch
simple sugars/monosaccharides= glucose
Food is used by living things as energy to drive all the processes going on
in living things and as matter/mass to build all the parts of living things
Do decomposers respire? If so, what waste product do they give off in cellular
respiration? Where would a gaseous waste product of cellular respiration go?
Give this one a try later!
Yes it is a living thing so it respires releasing carbon dioxide into the
atmosphere through cellular respiration
Why is light not sufficient to support photosynthesis in condition A?
Give this one a try later!
no water present; can't break the hydrogen bonds into oxygen in light
reactions of photosynthesis
