Which of the following statements is true concerning catabolic pathways?
marysya [2.9K]

The options are incorrect. The correct question with options is:

Which of the following statements is true concerning catabolic pathways?

A. They combine molecules into more energy-rich molecules

B. They supply energy, primarily in the form of ATP, for the cell's work

C. They are endergonic

D. They are spontaneous and do not need enzyme catalysis

E. They build up complex molecules such as protein from simpler compounds

Answer:

B. They supply energy, primarily in the form of ATP, for the cell's work

Explanation:

Catabolic pathways are the metabolic pathways that breakdown the complex molecules into simpler substances. The chemical reactions of catabolic pathways are mostly exergonic with a negative value of free energy change.

The released energy is stored in the form of ATP molecules. The energy-releasing reactions of catabolic pathways supply the cells with ATP molecules to perform the functions. For instance, breakdown of glucose into CO2 and H2O during aerobic cellular respiration is a catabolic process and forms as many as 32 ATP molecules.

2. Evaluate Claims A student claims that the four types of macromolecules make up all of
bearhunter [10]

Answer:

Yes, our body is made up of four Macromolecules.

Explanation:

Yes, the claim of the student is right that Macromolecules such as carbohydrates, lipids, proteins, and nucleic acids makeup the human body because all the cells are made up of carbohydrates, lipids, proteins, and nucleic acids. We know that our body is made up of cells so we can say that our body is made up of four Macromolecules. For example, our muscles are made up of protein, the fats present in our body are the lipids, carbohydrates are stored in the form of glycogen In liver and nucleic acids are present in the form of DNA and RNA.

how does the second law of thermodynamics help explain the diffusion of a substance across a membrane?
Damm [24]

The second law is the trend toward randomization, or increasing entropy.  

Second law allows for diffusion because diffusion is an increase in entropy .Diffusion is the process of movement of molecule down the concentration gradient until they doesn't exist . This movement represents an increase in the entropy.

Second Law of Thermodynamics state that molecules will spontaneously move towards an area of lower concentration, from an area of higher concentration. Molecule are capable to travel across cell membranes known as lipophilic molecules as they dissolve in the lipid bilayer. Movement represents an increase in the entropy or disorder in the system .
