What is the role of energy in chemical reactions?
energy is released or absorbed.
Which best describes the role of enzymes in chemical reactions?
to increase the reaction rate
Which is role of photosystem in the light reactions?
to make energy-carrier molecules like NADPH Apex
What is the role of a chemical bond in a energy transfers?
The amount of energy required to break a bond and produce neutral atoms is called the bond energy. It harbors the energy.
Which part of an atom plays a major role in chemical reactions?
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
What is the role of energy in chemical reactions?
energy is released or absorbed.
What describes the role of sunlight in chemical reactions?
it provides energy for some reactions to take place.
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
Describe the role that enzymes play in the process of metabolism?
Enzymes increase the rate of the chemical reactions carried out during metabolism.
Role of chlorophyll in photosynthesis?
Clorophyll collects the light energy that is used to fuel and start the chemical reactions for photosynthesis.
What is the role of oxygen in chemical reactions?
it makes you breathe
What is the role of light in photochemical reactions?
it provides energy
What is the role of activation energy in inorganic chemistry?
Activation energy is needed to trigger some non-organic chemical reactions, For example the use of a blasting cap to detonate high explosives.
What is the role of energy in living organisms?
Your thinking is perhaps confused, you seem to imply that energy is carried around by organisms in a sort of bag, or some part of the body, like a packet of cookies. Energy is generated or absorbed by each of the multitude of chemical reactions continuously taking place in the body. Those chemical reactions are what constitute a living being.
What are enzymes What is their role in a cell?
Enzymes speed up chemical reactions.
What is the major role of proteins in the body?
To function as enzymes (in chemical reactions).
How chemicals play an important role in the physiological aspect of the body?
Enzyematic reactions that occur from chemical reactions in the body speed up the activity and physiologically have everything to do with chemical reactions in the body.
