During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes.
In order for this to occur, which of the following statements must be true? A.
The new compounds that are formed must be more complex than the food molecules that were broken down.
B.
New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
C.
New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.
D.
The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.
B. New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
Explanation:
The correct statement from the given choices is that new compounds with lower-energy bonds must be formed when the high- energy bonds in the food molecules are broken down.
Cellular respiration is classified as an catabolic process in which an energy rich substance is broken down into a lesser one.
Metabolic processes are usually divided into catabolic and anabolic processes.
In catabolic step, energy is broken down.
Cellular respiration is catabolic whereas photosynthesis is anabolic.
The new compounds formed have lower energy bonds after respiration.
1. ridges and trenches (either answer is acceptable)
2. mid-atlanitc
3. subduction zone
4. molten
5. oceanic trenches
Explain:
6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.
To make proteins, DNA transcribes information into RNA in the nucleus. Transcription is like making copies of the information from DNA and applying this information in a new format. The RNA exits the nucleus and travels through the cytoplasm to ribosomes on the rough endoplasmic reticulum
