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.
Answer;
The similarity between gills and lungs is that both are sites for gaseous exchange in living organisms.
Explanation;
Gills is a site for gaseous exchange in fishes amphibians at some stage in life; while the lungs is a site of gaseous exchange in mammals and other organisms such as reptiles.
They both serve to bring in oxygen in the living things body and the eliminate carbon dioxide from the body; process of gaseous exchange.
However, they differ in a number of ways; for example, lungs are internal while gills are external , lungs are developed to breath in oxygen from the air, while gills are developed to get oxygen from water.
Without lysosomes, the cell would not be able to break down no longer functioning cellular components, other wastes, or foreign invaders. The buildup of those wastes would kill the cell, as would a pathogen that cannot be killed by that cell.
Answer:
Option B, A phosphatase removes the phosphate group from phosphorylated amino acid residues in a protein.
Explanation:
A phosphatase enzyme is responsible for removing phosphate group from a protein.
This usually happens during the chemical process of hydrolysis in which phosphomonoester is hydrolysed using phosphatase as a catalyst..
The final output of this reaction are -
a) Phospahte ion with OH group attached to it
b) H+ ion attaching to the hydroxyl group of the other product.
c) Splitting of water
Option B is correct
Those would be enzymes I believe. They are the power house of the membrane and lower the amount of activation energy needed.
