Biology Terms: Cell Division, Proteins, Metabolism, and Photosynthesis, Quizzes of Biology

Definitions for various biology terms including cell division processes (crossing over, anaphase i, metaphase ii, prophase, asters), proteins, metabolic reactions (anabolism, catabolism, oxidation, reduction), elements (carbon, hydrogen, oxygen), metabolic reactions (aerobic respiration), enzyme properties (active site, allosteric enzyme), mutations (point mutation), and photosynthesis (thylakoid, feedback inhibition).

Crossing over

recombination occurs between the genes on the sister

chromatids of homologous pairs

TERM 2

Anaphase I

DEFINITION 2

homologous chromosomes migrate to opposite poles

TERM 3

Only metaphase

II

DEFINITION 3

duplicated chromosomes singly line up during meiosis

TERM 4

protein

DEFINITION 4

macromolecule with the highest diversity of funcitons

TERM 5

peroxisomes

DEFINITION 5

membrane bound vesicles that contain enzymes for oxidizing

small organic molecules with the formaiton of hydrogen

peroxide

binary fission

how a bacteria divides

TERM 7

prophase

DEFINITION 7

phase of mitosis in which the nuclear membrane disappear

and the chromosomes become distinct

TERM 8

asters

DEFINITION 8

arrays of short microtubules that radiate from the poles and

may brace the centrioles against the membrane

TERM 9

Carbon, Hydrogen, Oxygen

DEFINITION 9

primary elements used to build the human body

TERM 10

Oxidation

DEFINITION 10

when an atom/molecule loses an electron

Allosteric enzyme

by binding a regulatory molecule, it changes the activity of a

metabolic pathway

TERM 17

point mutation

DEFINITION 17

affects a single site in the DNA

TERM 18

E site

DEFINITION 18

binds the tRNA that carried the previous amino acid added.

The final binding site

TERM 19

Phosphorylation

DEFINITION 19

attaches a phosphate group by a high energy bond

TERM 20

Thylakoid

DEFINITION 20

A thylakoid is a membrane-bound compartment inside

chloroplasts and cyanobacteria.
