those that break down organic molecules for energy

those that build up organic molecules to store energy for later use.

a chemical pathway in which organic molecules

are broken down to release energy in a quickly usable form (ATP).

Cellular respiration can be divided into?

two basic categories, aerobic and anaerobic.

uses molecular oxygen (O2) as the final electron acceptor in the reaction pathway.

Anaerobic pathways do not use?

oxygen as they perform respiration;

anerobic respiration and fermentation

they are processes celluar respiration that does not use oxygen

Aerobic Respiration formula is?

C6H12O6 + 6O2 + 6H2O → 6CO2 + 12H2O + energy (ATP)

Photosynthesis formula is?

6CO2 + 12H2O + energy (light) → C6H12O6 + 6O2 + 6H2O

Glycolysis is the first stage of aerobic respiration, but it is also a part of all other known cellular respiration pathways. It involves the conversion of glucose (C6H12O6) into two 3-carbon molecules of pyruvate.

The formation of acetyl CoA

The formation of acetyl CoA involves the conversion of each pyruvate into acetyl-CoA, releasing one CO2 for each pyruvate reactant

The citric acid cycle

The citric acid cycle oxidizes the remaining carbon atoms of each acetyl-CoA to CO2.

Oxidative phosphorylation

During each of the first three stages, the original organic carbon atoms are oxidized to CO2 as their electrons are collected into the high energy compounds NADH and FADH2.

The electron transport chain?

is a series of membrane complexes that transfers energy-rich electrons from one complex to another in a chain.

The energy from the electrons is used to?

pump protons across the inner mitochondrial membrane.

transmembrane enzyme called?

ATP synthase couples the energy provided by the movement of these protons down their electrochemical gradient to synthesize ATP.

Though aerobic respiration is much more efficient

making up to 36-38 total ATPs per glucose molecule, some organisms live in environments where oxygen is lacking.

Anaerobic respiration,

a pathway present in some prokaryotes, is remarkably similar to aerobic respiration.

In fermentation, the reactions of glycolysis still occur,

making 2 ATPs by substrate-level phosphorylation.

light energy is converted into an organic molecule form such as glucose.

Plants, algae, and some kinds of bacteria are?

capable of performing photosynthesis.
