What is chemical digestion
What is chemical digestion?

  • Changing big nutrient molecules into their smaller building blocks

  • REQUIRES ENZYMES

  • Example: Proteins broken down into amino acids. Proteins and amino acids are different substances.


Where does chemical digestion occur and name the enzyme found in each location
Where does chemical digestion occur and name the enzyme found in each location

  • Mouth- salivary amylase

  • Stomach - pepsin

  • Small intestine- amylase, lipase, protease


What is mechanical digestion
What is mechanical digestion? found in each location

  • Food is broken into smaller pieces by teeth or churning

  • Big protein molecules broken down into smaller protein molecules

  • Big fat molecules broken down into smaller fat molecules


Where does mechanical digestion take place
Where does mechanical digestion take place? found in each location

  • Mouth

  • stomach


What types of organisms do cell respiration

What types of organisms do cell respiration? found in each location

All Living things- grass, trees, birds, dogs, cats, gorillas, monkeys, bugs, etc etc.


Give an example of a catalyst

Give an example of a catalyst found in each location

Any enzyme!

Catalysts are things that speed up reactions


In this sentence what does catalyze mean how do enzymes catalyze reactions

In this sentence what does catalyze mean? found in each locationHow do enzymes catalyze reactions?

Speed up


What is the equation for a catalyzed reaction

What is the equation for a catalyzed reaction? found in each location

Enzyme + substrate --> enzyme + product

*** the substrate is what is broken down into product (example: H202 broken into H20 and O2


Can enzymes ever be used up

Can enzymes ever be used up? found in each location

NO. Enzymes are never used up and are not changed from reactions.


How many substrates can an enzyme work on

How many substrates can an enzyme work on? found in each location

ONE! Enzymes are specific, they only attach to one substrate. Just like a key only goes with one lock.


What had a faster reaction raw or cooked liver why

What had a faster reaction- raw or cooked liver? Why? found in each location

Raw liver. Liver has enzymes in it. Cooked liver means the liver was in heat. Heat causes enzymes to denature which means they lose their shape. Enzymes must have an exact shape (like a key) to work


What conditions have an impact on how well enzymes work

What conditions have an impact on how well enzymes work? found in each location

pH (acidity and basic) and temperature. Enzymes like to be in a certain range. If enzymes are in environments that are too hot, too cold, too acidic or too basic they won’t work as well and might not work at all


In the lab what items had catalase hydrogen peroxidase in them

In the lab, what items had catalase (hydrogen peroxidase) in them?

Catalase (hydrogen peroxidase) is an enzyme. All enzymes are found in living things. So they would be found in: raw liver and cooked liver


Hydrogen peroxide is made by reactions in our body and is dangerous to our cells. It must be broken down by the enzyme hydrogen peroxidase

What order does food travel through the digestive tract beginning with the mouth

What order does food travel through the digestive tract beginning with the mouth?

Mouth then esophagus then stomach then small intestine then large intestine then rectum then anus


What are the 3 major groups of nutrients

What are the 3 major groups of nutrients? beginning with the mouth?

Carbohydrates, lipids (fat), protein


Where are the salivary glands located

Where are the salivary glands located? beginning with the mouth?

Mouth


This connects mouth to stomach

This connects mouth to stomach beginning with the mouth?

Esophagus






This is where wastes are produced

This is where wastes are produced enzymes

Large intestine


Here you can find villi

Here you can find villi enzymes

Small intestine


This produces bile

This produces bile enzymes

liver



Are vitamins and minerals considered nutrients where are they absorbed

Are vitamins and minerals considered nutrients? enzymesWhere are they absorbed?

They are not nutrients because they do not have calories

They are absorbed in the large intestine


The places where no digestion occur

The places where no digestion occur enzymes

Esophagus, liver, gallbladder, pancreas, large intestine, rectum






Last place where digestion occurs

Last place where digestion occurs nutrients

Small intestine



In this spot, nutrients such as amino acids, fatty acids and simple sugars are small enough to pass into villi

Small intestine


This is where reabsorption of water occurs

This is where reabsorption of water occurs simple sugars are small enough to pass into villi

large intestine



This is a triple threat proteins lipids and carbs can be broken down chemically here

This is a triple threat- proteins, lipids and carbs can be broken down chemically here

Small intestine



What is the flap that covers the opening to the wind pipe trachea when you are swallowing food

What is the flap that covers the opening to the wind pipe (trachea) when you are swallowing food?

Epiglottis



Here you can only find simple sugars

Here you can only find simple sugars making enzymes

Mouth (because in mouth ONLY carbs are broken down into simple sugars by amylase)


Here you can find amino acids fatty acids and simple sugars

Here you can find amino acids, fatty acids and simple sugars making enzymes

Small intestine (because carbs are broken down into simple sugars by amylase; proteins are broken down into amino acids by protease and lipids broken down into fatty acids by lipase)




This is where proteins are broken down into amino acids by the enzyme pepsin

This is where proteins are broken down into amino acids by the enzyme pepsin

Stomach because enzyme pepsin is made by stomach




Is bile an enzyme what does it break down

Is bile an enzyme? What does it break down? enzymes

NO; it breaks down fats by mechanical digestion. It takes big lipids (fats) and turns them into smaller pieces of lipid (fat)


This is where carbs are broken down into simple sugars by the enzyme pancreatic amylase

This is where carbs are broken down into simple sugars by the enzyme pancreatic amylase

Small intestine





How do enzymes cause reactions to go faster

How do enzymes cause reactions to go faster? occur

They lower the energy needed for the reaction to start (enzymes lower the activation energy)



Where you can find gastric juice

Where you can find gastric juice enzyme lipase

stomach



What are the 3 biomolecules nutrients

What are the 3 biomolecules (nutrients)? enzyme lipase

During anaerobic respiration no oxygen present what happens

During anaerobic respiration (no oxygen present) what happens?

Instead of the krebs cycle and electron transport chain, glucose is changed into lactate (lactic acid)

Krebs cycle gives two

Electron transport chain gives 34


What happens in glycolysis

What happens in glycolysis? happens?

Goes in : Glucose (C-C-C-C-C-C) a 6 carbon molecule is split into 2. Each new molecule C-C-C is called pyruvate
