DAT Biology 2025/2026 Exam Questions
with 100% Correct Answers | Latest
Update
Carotenoids - 🧠ANSWER ✔✔lipid derivatives, produce pigments in plants
and animals , An accessory pigment, either yellow or orange, in the
chloroplasts of plants. By absorbing wavelengths of light that chlorophyll
cannot, carotenoids broaden the spectrum of colors that can drive
photosynthesis.
Porphyrins - 🧠ANSWER ✔✔lipid derivatives, a group of light-sensitive,
pigmented, ringed chemical structures that are required for the synthesis of
hemoglobin. Complexed with metals usch as iron in hemoglobin and
chlorophyll with Mg
Can H20 and hydrocarbons pass freely across membrane? - 🧠ANSWER
✔✔yes (small, uncharged, non-polar, hydrophobic can pass)
,Porins - 🧠ANSWER ✔✔allow passage of certain ions and small polar
molecules such as aquaporins in kidneys for H20
Rough ER - 🧠ANSWER ✔✔protein synthesis, creates glycoproteins for
secretion
Smooth ER - 🧠ANSWER ✔✔synthesis of hormones, lipids, breakdown of
toxins and drugs in liver
cyclosis - 🧠ANSWER ✔✔transport of material in cytoplasm (steaming
movement)
Peroxiomes - 🧠ANSWER ✔✔breakdown of H2O2, fatty acids, AA. In liver
and kidneys to break down toxins, by-products of photorespiration in plants
Centrioles - 🧠ANSWER ✔✔two tiny structures located in the cytoplasm of
animal cells near the nuclear envelope; play a role in cell division. Are
microtubles (MTOCs)
Storage vocuoles - 🧠ANSWER ✔✔store starch, pigments, toxic substances
(nicotine) in plants
Contractile vacuoles - 🧠ANSWER ✔✔in single cell organism, pump excess
water out of cell Ex. fresh water protozoa to prevent bursting
, Desmosome - 🧠ANSWER ✔✔aka spot welding, support and stability
Tight junctions - 🧠ANSWER ✔✔animal cells, seal to prevent passage of
materials btwn cell
gap junctions - 🧠ANSWER ✔✔narrow tunnels btwn animal cells, only ions
exchange
plasmodesma - 🧠ANSWER ✔✔barrow channels between plant cells for
exchange of materials
Bulk flow - 🧠ANSWER ✔✔collective movement of substance (like blood or
urine) in same direction due to force
dialysis - 🧠ANSWER ✔✔diffusion of solutes across selective permeable
membrane (passive)
plasmolysis - 🧠ANSWER ✔✔water of out cell, results in collapse aka shrivel
(passive)
Total ATP in Eukaryotic and Prokaryotic - 🧠ANSWER ✔✔Eukaryotic = 36
ATP Prokaryotic = 38 ATP
Glycolysis - 🧠ANSWER ✔✔1 glucose + 2 ATP + 4 ADP + 2NAD + 2Pi --> 2
pyruvate + 2ADP + 4 ATP + 2NADH +2H + 2H2O = 2 ATP
3
