Question

1. which statement best compares a function of proteins and lipids in a human cell? proteins catalyze chemical reactions inside the cell. lipids allow for the transport of certain molecules into and out of the cell. proteins store genetic information for cells. lipids provide energy for cellular processes. proteins provide energy for cellular processes. lipids catalyze chemical reactions inside the cell. proteins allow for the transport of certain molecules into and out of the cell. lipids store genetic information for cells. clear all

Explanation:

Proteins can act as transporters to move molecules across the cell - membrane. Lipids are important for forming the cell - membrane structure but do not store genetic information (which is done by nucleic acids), proteins do not store genetic information either. Enzymes (a type of protein) catalyze chemical reactions, not lipids. Carbohydrates are the main energy - source for cellular processes, not proteins or lipids in the primary sense.

Answer:

Proteins allow for the transport of certain molecules into and out of the cell. Lipids store genetic information for cells is incorrect as lipids don't store genetic info. Proteins store genetic information for cells and Lipids provide energy for cellular processes are incorrect as stated above. Proteins provide energy for cellular processes and Lipids catalyze chemical reactions inside the cell are also incorrect. So the correct understanding is that proteins can be transporters and lipids have membrane - related functions but not the ones wrongly attributed in other options.
