Relationship between photosynthesis and cellular respiration

products of one are the reactants of the other

Fermentation

NAD+ is regenerated allowing glycolysis to continue

Molecule Krebs cycle starts with

pyruvic acid

Alcoholic fermentation: used to make what products?

alcohol & bread

Molecules that pass high energy electrons to ETC

NADH & FADH2

Type of fermentation for a 1 minute race

lactic acid fermentation

Organelle where cellular respiration takes place

mitochondria

Electron carrier in cellular respiration

NAD+

Mastered (2)

[SHORT ANSWER] Role of oxygen in ETC

gets rid of low energy electrons and H+

Molecule that electrons end up forming

water

Metaphase: what happens?

chromosomes line up in the middle of the cell

Cell to cell contact

cells stop growing when they come in contact with each other

Phases of mitosis

PMAT (prophase, metaphase, anaphase, telophase)

Example of external regulators

growth factors

Explain what happens when cancer occurs to cell cycle

control of the cell cycle is impaired/damaged

Know what happens in G1, S, G2, and M phases

G1 = cell grows

S = DNA is replicated

G2 = prepares for mitosis

M = cell division

Centromere

attachment for sister chromatids

Type reproduction that mitosis is: sexual or asexual?

asexual

Centriole

forms spindle fibers

Interphase

G1, S, G2
