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.
Cellular respiration is the process of synthesizing cellular energy (ATP) from organic sources such as water, glucose and oxygen. These substances are processed through a series of steps in order to produce ATP. The main organelle responsible for ATP synthesis is the mitochondria.
<span>In plants, the photosynthetic pigment, chlorophyll, is found within chloroplasts. The process of photosynthesis is driven by light and carbon dioxide from the environment, converting these into glucose, water and energy. </span>
<span>photosynthesis occurs in chloroplasts </span>
<span>cellular respiration occurs in mitochondria</span>
Answer:
The answer is Letter A
Explanation:
There is no threat to the city water, but there is a likely health threat when the chemical moves to the surface outcrops of the layers the spill occurred in.
They are the energy base of the food chain for all aquatic organisms, without them all aquatic organisms would most likely parish.
