Which proteins speed up chemical reactions

Enzymes are proteins that speed up chemical reactions.

Why do living things use enzymes instead of heat as a source of activation energy

Adding sufficient heat would harm or kill a living thing. also enzymes are far more efficient. A single enzyme can often carry out thousands of reactions per second. Living organisms use enzymes for activation energy because they speed up chemical reactions.

A triglyceride is made up of three fatty acids and one molecule of what

A triglyceride is made up of three fatty acids and one molecule Glycerol, C3H5(OH)3.

Which best describes the role of enzymes in chemical reactions

to increase the reaction rate

What is activation energy How does a catalyst affect activation energy

Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.

Improvement:

A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.

* = as a result of the interaction of the reagents with the catalyst.

What is characteristic of unsaturated fats

One characteristic of unsaturated fats is that they are liquids at room temperature.
