The two chemicals required for cellular respiration in all living things are?

Cellular Respiration Overview

Cellular respiration is an aerobic process requiring oxygen.
It occurs in both autotrophs (organisms that produce their own food) and heterotrophs (organisms that consume food).

Key Structures

Photosynthesis occurs in chloroplasts, while cellular respiration takes place in mitochondria.

Glycolysis

Glycolysis results in a net gain of 2 ATP.
It requires ATP for initiation and takes place in the cytoplasm.

Krebs Cycle

The Krebs cycle begins with pyruvic acid and produces carbon dioxide as a byproduct.

Electron Transport Chain

Occurs in the inner mitochondrial membrane, responsible for producing the majority of ATP during cellular respiration.
The net gain of ATP from the electron transport chain is 32, contributing to a total of 36 ATP produced in aerobic respiration.

Fermentation

Lactic acid fermentation happens in muscle cells when oxygen is scarce, such as during intense physical activity.
In humans, fermentation occurs when skeletal muscle cells lack oxygen.

Energy Production

Aerobic respiration, which utilizes oxygen, forms the greatest number of ATP compared to anaerobic processes.
The molecular products of cellular respiration include ATP, carbon dioxide, and water, where ATP is a key energy carrier.

Key Chemicals

Essential chemicals for cellular respiration include glucose and ATP.
Plant cells utilize oxygen primarily for aerobic respiration.

Summary of Energy Release

In a bean plant, aerobic respiration of glucose yields the highest energy output compared to other reactions.

Overall Importance

Understanding cellular respiration is crucial for comprehending how organisms convert food into energy and the role of various cellular structures in this process.
