Hello students, city will be solving a question in biology.
00:03
As you can say from the question they have given us a set of options and we have to identify the functions of phytochemicals.
00:09
So this question is about identification of functions of a group of chemicals called as phytochemicals.
00:27
Now phytochemicals are nothing but chemicals that are obtained from plants.
00:31
Okay, phytochemicals are nothing but chemical components that are obtained from plants.
00:43
Chemical components or compounds obtained from plants as they are not synthesized and found in animal sets.
00:56
So, options they've given us are in humans some phytochemicals block tumors while other interferes with initiation phase of cancer development and this is for.
01:05
Through okay, phytochemicals are natural antioxidants.
01:11
These phytochemicals are natural antioxidants.
01:20
And since they are being natural antioxidants, they are protecting dna from environmental carcinogens.
01:29
Okay, they can protect dna from environmental carcinogens.
01:44
They can protect dna from environmental carcinogen because if you don't if you see a mechanism on free radical attack free radicals okay are substances which are forming in the human body they can form by various metabolic processes in the human body as well based on the food we consume or they can occur due to environmental pollutants they can occur due to pollutants that we consider carcinogens and they they can also be due to x -rays, uv rays, gamma rays or can also do to inhaling of various chemicals.
02:25
So all these substances helps in increase in number of free radicals in human body.
02:32
So these free radicals are substances with oxygen in them.
02:36
They have o2 in them as a central atom and they have uneven electrons.
02:43
They have uneven number of electrons.
02:50
Now since they have uneven number of electrons, they have ability to freely react.
02:56
They have the ability to freely react...
