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.
Are most chemical reactions at equilibrium in living cells?
No, most chemical reactions in living cells are not at equilibrium. Cells maintain a dynamic balance, constantly adjusting reaction rates to respond to changing conditions and maintain homeostasis. Equilibrium is rare in living systems due to the constant flux of molecules and energy.
Why are enzymes used to perform hydrolysis in living systems?
Enzymes are used to perform hydrolysis in living systems because they speed up the breakdown of complex molecules into simpler ones. The presence of enzymes reduces the activation energy required for these reactions to occur, making the process more efficient. This allows organisms to obtain nutrients and energy from food sources more effectively.
What is the totality of chemical reactions that occur in a living organism?
metabolism
How does the process of catabolic exergonic reactions contribute to the release of energy in living organisms?
Catabolic exergonic reactions break down molecules in living organisms, releasing energy stored in those molecules. This energy is then used by the organism for various biological processes, such as growth, movement, and maintaining body temperature.
What Organic molecules that catalyze reactions in living systems are?
Enzymes are the organic molecules that catalyze reactions in living systems. They act as biological catalysts by decreasing the activation energy required for a chemical reaction to occur. Enzymes are typically specific to particular substrates and can speed up reactions by many orders of magnitude.
The activation energy for the chemical reaction in living thing is high or low?
The activation energy for chemical reactions in living things is typically low compared to non-biological reactions. This is because living organisms rely on enzymes to catalyze reactions, lowering the energy barrier needed for the reaction to occur. This allows for faster and more efficient processing of biological molecules.
What are the reactions that deal with energy in a living thing referred to as?

Do Chemical reactions only occur in living organisms?
No, chemical reactions occur in both living and non-living systems. In living organisms, chemical reactions are essential for metabolic processes, while in non-living systems, chemical reactions can occur in various environments such as inorganic chemical reactions in the environment.
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.
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.
Why are endergonic and exergonic reactions are said to be coupled in living cells?
Endergonic reactions absorb energy, while exergonic reactions release energy. In living cells, these reactions are coupled so that the energy released from exergonic reactions can be used to drive endergonic reactions. This coupling allows cells to maintain energy balance and perform essential functions.
What is the chemistry of living systems representing all chemical reactions called - A. catabolism B. anabolism C. metabolism D. enzymology E. thermodynamics?
C. metabolism. Metabolism encompasses all the chemical reactions that occur within living organisms, including both catabolism (the breakdown of molecules for energy) and anabolism (the synthesis of compounds necessary for growth and maintenance). It is essential for maintaining the energy balance and cellular functions in 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.
What substance plays in major role in most chemical reactions in living system?
Enzymes are the substances that play a major role in most chemical reactions in living systems. Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy needed for the reaction to occur. They are crucial for maintaining the processes necessary for life.
What do chemical reactions in living organisms need to start?
Chemical reactions in living organisms require a source of energy to start. This energy is typically obtained from molecules such as ATP. Additionally, enzymes play a critical role in catalyzing these reactions by lowering the activation energy required for the reaction to occur.
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.
