Answer:
Explanation:
Cells generate energy from the controlled breakdown of food molecules. ... View Terms of Use molecules that other cells rely on for the energy required to sustain growth, metabolism, ... proteins that span the cell membrane permit specific molecules into the cell, Figure 2: Cells can incorporate nutrients by phagocytosis.
The proteins that helps in decreasing the activation energy of a reaction to occur at a definite temperature range and pH value in a living cell are called as the enzymes. These proteins are considered as the biocatalysts. All these biocatalysts are made up of proteins. All the enzymes are proteins but all proteins are not enzymes. Hence the answer is enzymes.
