Aerobic and Anaerobic Respiration

prokaryotes

Aerobic respiration takes place in all plants, animals, birds, and humans, except for some primitive

aerobic respiration

where oxygen acts as an electron acceptor which helps produce ATPs more effectively and more quickly

higher energy

The double bond in the oxygen has _________ than other bonds which aids to produce more ATPs.

Kreb’s cycle

It is the preferred method of degradation of pyruvate after glycolysis where the pyruvate then enters the mitochondria to be fully oxidized during the

oxidation of carbohydrates

The process of aerobic respiration is utilized for the _____________, but products from fats and proteins are also used as reactants

Carbon dioxide gas and water

are the two products of aerobic respiration along with the energy that is used to add a third phosphate group to ADP and form ATP

electron transport chain

Other energy-rich molecules like NADH and FADH2 are converted into ATP via _________ with oxygen and protons

oxidative phosphorylation

electron transport chain is also called as?

oxidative phosphorylation

Part of aerobic respiration where most ATP are generated

38

Ideally, a total of ____ ATPs are produced at the end of the aerobic respiration

Leaking of the membrane or the cost of moving pyruvate through the cell, as a result produces ______ which about 29 30 ATPs are only produced.

mitochondria

Aerobic respiration results in complete oxidation of carbohydrate molecules which take place in the __________

Anaerobic respiration

is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives

Anaerobic respiration

is the process of creating energy without the presence of oxygen

sulfate ion (SO4–) or nitrate ion (NO3–)

In anaerobic respiration, the electron acceptor can be _________ or a variety of other molecules

methanogens

Some archaea, called ______, are known to use carbon dioxide as the electron acceptor, producing methane as a by product

nitrate

The _______ that acts as an electron acceptor in anaerobic respiration produces nitrogen gas as a by-product, and this process is the only route for fixed nitrogen to reach the atmosphere

Fermentation

is another pathway for anaerobic respiration, where the only energy extraction pathway is glycolysis, and the pyruvate is not further oxidized via the citric acid cycle.

NADH

The energy-rich molecule, _______, is also not utilized during fermentation

2

A total of ____ ATPs are produced at an anaerobic respiration.

Aerobic respiration is __________ than Anaerobic respiration, in its time frame.
