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.
Explanation:
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
Answer:
Energy can change from one type to another.
Answer: 60 to 100 beats per minute.
Explanation:
Pulse is the number of times the hear pump blood out into the systemic circulation per minute
The lower this range the more efficient the heart is. In trained athletes the pulse rate is about 40bpm.
This shows the heart pumps blood at a faster rate to meet the demands of the muscles and other organs involved in the strenuous activities.
It can be measured by placing two fingers on the thumb side of the wrist,and count numbers of beats heard for 15 seconds.The counted number should multiplied by 4 to obtain beats per minute.
