Learn how we digestive enzymes such as amylase, proteases and lipases to break down carbohydrates, proteins and lipids. We also cover where the enzymes are made and what they break each food group down to.

I had an exam last week and I was unable to study. My friend suggested you channel and all you did was teach me exactly what my biology professor taught by much shorted and much better with those cute little images and i was able to get a 94 for my last biology paper of 9th grade.
I just came here to thank you so much cause if it wasn't for your videos i would have screwed up XD.

my notes if u need: Digestive enzymes
- enzymes are essential for helping break down the foods we eat
- Carbs are found in pasta, potatoes, rice and our body uses it as our energy source. Main type is starch ... Broken down by a enzyme called Amylase... Into smaller sugars like maltose...amylase is made in 3 places ... Salivary glands, pancreas and small intestine
- Protiens are found in nuts, meats and beans... Broken down by protease... Into amino acids...protease made in 3 places... Stomach (pepsin), pancreas, small intestine

[palaquium]

Lipases are also produced in the stomach, however they only broke down fats in form of emulsions (drops of oil digested directly for example)

I get the worst teachers in the most important subjects, thank you for saving me

I have been trying to do work on enzymes for a while tonight and nothing was rly sticking in my brain until i watched ur video u explained everything slowly enough for me to get and it rly did help. tyssm

[monicah]

Lipase is made by salivary glands as well. Lingual lipase to be specific...although it is not "activated" until it reaches the stomach (due to the low pH).

Get this man more recognition. He deserves it
