What else can I help you with?
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
Which statement will be describe how enzymes effect chemical reactions?
Enzymes lower the activation energy needed to start a chemical reaction.
Role of chlorophyll in photosynthesis?
Clorophyll collects the light energy that is used to fuel and start the chemical reactions for photosynthesis.
How it might be possible to start with copper and end up with coper after a series of chemical reactions?
It is impossible for copper to transform into "coper" through chemical reactions. Copper can undergo various reactions like oxidation or reduction, but it will always remain copper in its elemental form.
Enzymes affects the reactions in living cells by changing the?
Enzymes affect reactions in living cells by lowering the activation energy required for the reactions to occur, thus speeding up the rate of chemical reactions. They do this by binding to specific substrates and catalyzing the conversion of these substrates into products. This enables cells to carry out essential biological processes efficiently.
Do chemical reactions start with a reactant?
yes
What do enzymes do in the human body?
Enzyme: [n.] Any of numerous proteins or conjugated proteins produced by living organisms and functioning as biochemical catalysts.Enzymes allow chemical reactions to occur at normal body temperature by lowering the activation energy needed to start a reaction.
What energy needs to to start a chemical reaction?
It varies with the differences in chemical reactions
Do all chemical reactions need heat to start them?
no
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
What would happen if enzymes were not presented in the human body and other living things?
Without enzymes, biochemical reactions in living organisms would be extremely slow or not occur at all. This would lead to a breakdown in essential processes such as digestion, metabolism, and energy production, ultimately causing the organism to die. Enzymes play a crucial role in speeding up chemical reactions and maintaining life processes.
Where did all living organisms start?
A single cell.
Do all chemical reactions need heat to start them off?
No, not all chemical reactions require heat to start. Some reactions can occur at room temperature or even at low temperatures. Heat is often used to speed up reactions or provide enough energy to overcome the activation energy barrier.
How do emzymes speed up chemical reactions?
Enzymes lower the activation energy needed to start a chemical reaction.
How is activation energy relates to the start of chemical reactions?
A chemical reaction begin only if the activation energy has a specific value.
Which statement will be describe how enzymes effect chemical reactions?
Enzymes lower the activation energy needed to start a chemical reaction.
What is the term for the amount of energy that needs to be added for chemical reactions to start?
activation energy
