The reactions that produce molecular oxygen (O2) take place in the light-dependent reactions of photosynthesis, specifically in the thylakoid membranes of the chloroplasts. Here, water molecules are split through a process called photolysis, releasing oxygen as a byproduct.

When a log burns in a fire, what chemical reactions take place to produce heat and light?

When a log burns in a fire, the chemical reactions that take place involve the wood combining with oxygen in the air to produce heat and light. This process is known as combustion, where the wood undergoes a chemical reaction that releases energy in the form of heat and light.

What is needed for the energy releasing chemical reactions the take place inside your cells?

Energy-releasing chemical reactions inside cells require nutrients like glucose and oxygen, which are used in cellular respiration to produce ATP. Enzymes are also needed to catalyze these reactions and facilitate energy release from molecules. Lastly, proper functioning mitochondria are essential for carrying out the processes of cellular respiration to generate energy.


Are all combustion reactions redox reactions?

Sometimes, as during oxidation reactions oxygen is either added or hydrogen is removed from that particular element or compound undergoing the reaction. Combustion is burning taking place in the presence of oxygen so when the certain substance burns it is having oxygen added to it. Eg. 2Mg + O2 gives 2MgO Here Mg is getting oxidised and combustion is taking place as Mg is being heated in the presence of Oxygen.


What reaction takes place in the chloroplast?

Photosynthesis takes place in the chloroplast, where light energy is converted into chemical energy in the form of glucose. This process involves the absorption of light by chlorophyll molecules, which then drives a series of chemical reactions that produce oxygen as a byproduct.

What are the two reactions of aerobic cellular respiration?

The two main reactions of aerobic cellular respiration are glycolysis, which occurs in the cytoplasm, and the citric acid cycle (Krebs cycle), which takes place in the mitochondria. These reactions break down glucose to produce ATP, which cells use as energy.


How do cells make ATP with oxygen?

Cells produce ATP through aerobic respiration, which involves a series of chemical reactions that take place in the mitochondria. During this process, oxygen acts as the final electron acceptor in the electron transport chain, which generates a proton gradient used by ATP synthase to produce ATP. This overall process is known as oxidative phosphorylation.


Can you break oxygen bonds?

It is possible to break bonds between oxygen by supplying heat and this process takes place in all burning / oxidation reactions.


Were chemcal reaction takes place cell organelles?

Chemical reactions take place in various cell organelles. For example, in mitochondria, reactions like cellular respiration occur to produce energy. In the nucleus, reactions like DNA replication and transcription occur. And in the cytoplasm, reactions like protein synthesis take place.


What are the patterns of combustion reaction?

Combustion reactions involve a fuel (hydrocarbon) reacting with oxygen to produce carbon dioxide and water. The general pattern is: fuel + oxygen -> carbon dioxide + water. Combustion reactions are exothermic, releasing heat and light energy.
