I believe its the very last one or the very 1st one. sorry I could only give a 50/50 answer:/
Answer:
Melatonin
Explanation: melatonin in the body is a natural hormones that helps in the regulations or coordination of the cycle of our sleeping and waking. It is found in the pineal glad and it is more active during night time than day time.
Teenagers most especially has different time of sleep they sleep mostly late during weekends and sleep early during weekdays.our body needs sleep so as to function properly and most times our body is also adapt to some times that we sleep. Melatonin is usually release in the body gradually around 9pm in the evening where it initiate sleep but in some people, it is when the hormones is release in an increase dose that they can fall asleep thereby shifting the time to about 11pm or 12pm before the person can fall asleep for quick sleep, melatonin supplement are used.
Oranges are the best source of vitamin c
Answer:
The correct answer would be (B) Proteins will not fit into the active site of the amylase enzyme.
Enzymes are biocatalyst which accelerates the rate of a biochemical reaction.
They are highly specific to their substrate.
This high specificity is obtained with the help of the active site.
Every enzyme has the active site in which a particular substrate can fit or bind.
Similarly, salivary amylase also contains an active site which is specific for the polysaccharides like starch.
Proteins are not able to fit or bind to this active site due to which they are digested through amylase.
<span>The answer is:
Photosynthesis: 6 CO</span>₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP<span>
Cellular respiration and photosynthesis are
complement reactions to each other. These are reverse reactions. In
cellular respiration glucose (</span>C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite
reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and
oxygen (<span>O₂)</span><span>. </span>
