Answer:
TP synthesis in glycolysis: substrate-level phosphorylation
Explanation:
-One of the substrates is a molecule derived from the breakdown of glucose
-An enzyme is required in order for the reaction to occur
-A bond must be broken between an organic molecule and phosphate before ATP can form.
Incorrect:
-The phosphate group added to ADP to make ATP comes from free inorganic phosphate ions.
-The enyzmes involved in ATP synthesis must be attached to a membrane to produce ATP.
Answer: Characteristics of viral particles from the options given are;
1. Parasitic obligate.
2. The centre layer is predominate protein.
3.Genome may be RNA exclusively.
The characteristics of living cells are:
1 . May have cell wall.
2. Contain ribosomes.
3. Always of plasma.
Explanation:
Living cells are the basic unit of life, that contain the fundamental molecules in which the living things are composed of. Living cells have plasma membrane, ribosomes, cytoplasm and DNA.
Viral particle is a structure or infectious agents that enter another cell and replicates itself in a living cell. The are obligates parasite, that have no cell wall, they have center layer of protein, the genome contain either DNA or RNA, they reproduce only in living cells, they lack cytoplasm and organelles.
Answer:
A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."
C. After about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce ATP, resulting in "oxygen debt."
Explanation:
There are two sources of carbohydrates in the human's body for energy (ATP) production. 1) Creatine phosphate and 2) Glycogen. Creatine phosphate metabolizes easily and yields ATP quickly. Whereas glycogen is stored form of carbohydrate which yields energy more slowly. Therefore, initially, our bodies use creatine phosphate and then shift to glycogen. Within 60-90 seconds, the creatinine phosphate in the body is mostly utilized and then energy is produced by the use of glycogen in aerobic pathway. During areobic pathway, oxygen supply is sufficient and per cycle, it produces 32 molecules of ATP. However, when oxygen supply is limited or absent, the body will metabolize glycogen to lactic acid via fermentation and produce only 2 molecules of ATP.
Now consider the example: Kenny hikes all day at a steady pace therefore the supply of oxygen is sufficient for aerobic cellular respiration for ATP production. In this scenario, the oxygen debt is minimal and Kenny relies on aerobic respiration pathway to obtain energy. On the other hand, Janelle runs fast (100 meters in 13.5 seconds) and her cellular respiration would be on the compense of aerobic pathway initially which will be shifted to anaerobic pathway after the supply of oxygen is reduced/minimum. Janelle will heavily rely on the anaerobic pathway because running fast needs energy which cannot be provided via aerobic pathway easily. Therefore, Janelle's body will produce lactic acid and suffer from oxygen debt.
Answer:
abiotic conditions
Explanation:
yeah maybe a lightning storm could kill a few people but wont massivley affect a population
