UIUC IB 150 FINAL PAPER 2026 QUESTIONS
WITH FULL ANSWERS
◉ homeothermy. Answer: an organism that has a constant body
temperature
◉ hypothesis. Answer: statement that is testable that can examine a
set of observations or a phenomenon
◉ independent variable. Answer: variable that does not depend on
any external factor
◉ inner membrane (of mitochondrion). Answer: part of
mitochondrion where oxidative phosphorylation takes place
◉ R-selected strategy. Answer: type of organism that produces
multiple offspring at a given time that may allow outgrowing
carrying capacity
◉ kinetic energy. Answer: energy of motion that can vary in different
types including thermal, sound and mechanical
,◉ light dependent reactions. Answer: any of the 2 photosystems that
require light input for the reaction to proceed both NADPH and ATP
through photosystem 1 and ATP synthase respectively
◉ light-harvesting complex (of photosystems). Answer: array of
proteins that are anchored to the thylakoid membrane to harvest
light for the photosystems 1 and 2
◉ logistic growth. Answer: type of growth in which growth become
rapid over time but eventually approaches horizontal line (aka
carrying capacity)
◉ matrix. Answer: part of mitochondrion where the citric acid cycle
takes place
◉ mitochondrion. Answer: part of the cell where energy in the form
of ATP is produced
◉ mutualism. Answer: symbiosis that is beneficial to both organisms
involved
◉ NADPH. Answer: product of NADP+ reductase
, ◉ NADP+. Answer: NADPH before it has gained it electron from
ferredoxin
◉ NADP+ reductase. Answer: enzyme that catalyzes the chemical
reaction that makes NADPH
◉ net primary production (NPP). Answer: total amount of carbon
produced by photosynthesis that is not given off by cellular
respiration
◉ substrate-level phosphorylation. Answer: ATP production from
the phosphorated substrate within glycolysis
◉ oxidative phosphorylation. Answer: ATP production from a proton
gradient created by the electron transport chain
◉ photon. Answer: light particle
◉ photosynthesis. Answer: overall process where light energy is
converted into chemical energy in the form of glucose and gives out
O2 as a by product
◉ Photosystem 1. Answer:
