Answer 15

PLease 100000% correct please

Answer 16

29.cell wall and centriole
30.Glycolysis is the breakdown of glucose into two molecules of pyruvic acid,
producing 4 ATP molecules. An initial input of 2 ATP molecules is
required to start glycolysis; thus, there is a net gain of 2 ATP molecules.
This process produces high-energy electrons, which are passed to AND+
forming 2 NADH. If oxygen is present, glycolysis leads to the Krebs cycle
and the electron transport chain. If oxygen is not present, glycolysis is
followed by the rest of fermentation.
31.Facilitated Diffusion has to do with passive and active transport. Passive
Transport is the movement of molecules across the cell that does not require
expenditure of energy, however active transport is the movement of
substances across a membrane involving a carrier protein and energy from
respiration(ATP).
32.Anaerobic respiration is a type of respiration where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors.

Fermentation includes processes that use an organic molecule to regenerate NAD+ from NADH.

Types of fermentation include lactic acid fermentation and alcohol fermentation, in which ethanol is produced.

All forms of fermentation, except lactic acid fermentation, produce gas, which plays a role in the laboratory identification of the bacteria.

Some types of prokaryotes are facultatively anaerobic, which means that they can switch between aerobic respiration and fermentation, depending on the availability of oxygen.

TERMS

archaea
The Archaea are a group of single-celled microorganisms. They have no cell nucleus or any other membrane-bound organelles within their cells.

anaerobic respiration
Anaerobic respiration is a form of respiration using electron acceptors other than oxygen.

fermentation
an anaerobic biochemical reaction, in yeast, for example, in which enzymes catalyze the conversion of sugars to alcohol or acetic acid with the evolution of carbon dioxide
