Describe the role of teeth in increasing the surface area of complex foods for exposure to digestive chemicals

Amylase – Enzymes that break down carbohydrates
Protease – Enzymes that break down proteins
Lipase – Enzymes that break down lipids

Digestion begins in the mouth where teeth break the complex food into smaller pieces, this increases the surface area for exposure to digestive chemicals i.e. enzymes. Saliva then lubricates the food and the amylase digests starch to maltose.

how much more can i write on this.. i cant find nething else..

all its asking is for the role of the teeth: mechanical breakdown of food - increasing the surface area for exposure to the digestive enzymes you mentioned

thx.. wow.. u really no ur stuff..

 

[pLuvia]

You must spread some Reputation around before giving it to omigodwhenover again.

anmd one more thing.. the test was out of 45.. so i got 32.5 / 45

Explain the relationship between the requirements of cells and the need for transport systems in multicellular organisms

one more question .. then ive finished my dot points for bio..~~!

 

[omigodwhenover]

oh okay but i bet u do betta in ur yearlies cuz u are studying so hard now!

 

[pLuvia]

oh okay but i bet u do betta in ur yearlies cuz u are studying so hard now!

lol.. i usually do betta in yrlies.. .. dunno y.. how bout u .. wat u ranked?

 

[pLuvia]

Explain the relationship between the requirements of cells and the need for transport systems in multicellular organisms

so can u help me on this dot pt.. plz plzp plz

one more question .. then ive finished my dot points for bio..~~!

hmmm! thats kind of a hard one cuz im not up to it yet i dont think, how bout i get back to u i am nearly there..

Can you help me with this one? Its that last dot point for a local ecosystem:
* discuss startegies aimed at balancing the needs and activities of humans wiht the need to conserve, maintain and protect the environment

umm.. i cant find it newhere.. i thought the last dot pt for local ecosystems is.. identify the impact of humans in the ecosystem studied newayz.. ill help u neway...

umm..

• development of sustainable agricultureal practices
• recycling
• reduce production of greenhouse gases
• increased funding for expansion of national parks and wilderness areas
• composting
• organic farming
• laws to protect native species
• bush regeneration programs
• development of cheaper, efficient, renewable sources of energy e.g. solar energy and wind energy

well i hoped that helped..

 

[omigodwhenover]

thankyou i promise ill tell u when i get up to the same bit as you

 

[pLuvia]

thankyou i promise ill tell u when i get up to the same bit as you
