Why do energy processing reactions in living systems have to be REDOX reactions?

∙ 11y ago
This is how catabolic pathways decompose glucose and other organic fuels that yield energy, by substances giving off and accepting electrons energy is released and this is ultimately crucial for energy processing reactions in living systems. Redox reactions does just this by having reduction of electrons and oxidation of electrons occur in this reaction.

Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
Living things need a constant supply of energy even though many of the chemical reactions they undergo release energy why is this true?
the energy used/released in those reactions are used in other ways that the organism needs in order to survive.
What breaks down large molecules?
Larger molecules become smaller molecules by chemical reactions referred to as decomposition reactions. These can be as simple as oxidation, or as complex as catalyzed reduction of hydrocarbons (oil). The chemical reactions can be triggered by other reactive chemicals, by catalysts, or by the addition of energy (heat, electric current). They can be spontaneous or be deliberate, and they can sometimes be self-sustaining, as in a cascade reaction.
The energy stored in food molecules in living cells is gradually released in a series of linked chemical reactions called a?
ATP Generator
Chemical reactions in all living things?
Yes. Everything you do is caused by a series of complex chemical reactions. Turning the food you eat into energy you can you to run or do anything else for example.
What Organic molecules that catalyze reactions in living systems are?
Enzymes are organic molecules that catalyze reactions in living systems.
What are the reactions that deal with energy in a living thing referred to as?
what are the reactions that deal with energy in a living thign referred to as
What is energy requirements of living systems?
The energy requirements of living systems include being able to move. These living systems also need energy to eat and to hunt.
Why do living things need both endothermic and exothermic reactions in their bodies?
Living things have cellular reactions which involve both reactions in the process. Endothermic reactions help the body conserve energy or contain it. Exothermic reactions help the body produce energy.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
How living systems follow the law of conservation of mass and energy?
EXACTLY that same as non-living systems.
Why is it important that energy-releasing reactions take place in living organisms?
It is it important that energy-releasing reactions take place in living organisms because living organisms need energy. These energy releasing reactions allow the cell to capture the energy released during oxidative metabolism and store it as potential chemical energy.
Which is a type of protein that speeds up chemical reactions in living things?
An enzyme is a type of protein that speeds up chemical reactions in living things by lowering the activation energy of said reactions.
Enzymes affect the reactions in living cells by lowering the?
activation energy of the reaction.
The main source of energy for reactions that occur in all living organisms?
Atp
What do chemical reactions in living organisms need to start?
all they need is energy
What do most living things us to release energy from food?
chemical reactions.
