?Higher Co2 level

Photosynthetic humans
Hijacking the photosynthetic
pathway to humans :
1. Transfer of Genes that code for the chloroplast
function from plants
2. Transfer of Genes obtained from solar powered
sea slugs / cyanobacteria
E.g. Elysia chlorotica
3. Genetic Modification of melanin
1. Chloroplast Engineering
Light is the most important factor
1. Chloroplast Engineering..
? Requires
? The artificial chloroplast function in human skin
? Exposure to sun light (The average human being has 1.8m2
of skin, approximately half of which would be exposed to
the sun!)
? In photosynthesis, sunlight is captured and transported
by highly specialised antenna proteins.
? Not necessarily green light!
? Chloroplast genes can be identified and transferred to
the human skin continuously.
2. Genes from Elysia chlorotica
? lives in waters on the east coast of the USA and Canada
? is known to steal genes and photosynthesizing
organelles called chloroplasts
? has developed an entire chemical pathway to
manufacture the green pigment "chlorophyll" itself.
? Eats the algae, Vaucheria algae , just for once only and
supplies the chlorophyll and other chemicals used in
photosynthesis.

3. Genetic Modification of
melanin
?Melanin is just like chlorophyll to the animal kingdom
?Melanin is a pigment found in most organisms.
? In humans, melanin is the primary determinant of skin
color. It is also found in hair
?Melanocytes of human skin could be engineered to
produce another pigment, causing the skin to take on a
different colour.
3. Melanin
Can we form chemical energy in the form of ATP?
Bottle necks
?Insufficient studies
?The need of water
?Energy requirement
?Exposure of the skin
?Ethical reasons
? Hira Ratan Manek was born in 1937 and grew up in
Kerala, India, getting his Mechanical Engineering degree
from the University of Kerala. After graduation, he
joined the family business, which was shipping and
spice trading, and continued working there until he
retired in 1992. After he retired, he began to study sun
gazing, particularly the teachings of Lord Mahavir of the
Jains, who practiced this method two thousand six
hundred years ago. Since June 1995 HRM has lived on
sun energy, water and the occasional cup of tea or
buttermilk "for social purposes."
? He stopped eating solid food in 1995 and have baffled
the doctors and scientists who have studied him during
fasts of 211 and 411 days. How did he manage to do it?
? This is an ancient practice based on logic and modern
biological science that relies on water and sunlight for
energy. This is really photosynthesis taking place in the
human body, Hira Ratan;
Thank you!
