Unit 1
Hypertonic
In what type of solution will a cell will shrink?
Or
What type of solution contains higher solute concentration and lower water concentration outside the cell.
Water moves from an area of high concentration to an area of low concentration.
What is osmosis?
This is the third main organ/area of the alimentary tract.
What is the esophagus?
Food is rolled into this at the back of the tongue before swallowing occurs.
What is a bolus?
This enzyme is active in breaking down carbs in the mouth.
What is salivary amylase?
Receptor, carrier, and channel proteins
This is the process heterotroph cells engage in to use energy.
What is cellular respiration?
This process is used to physically move food through the alimentary tract.
What is peristalsis?
Partially digested food passes through this before entering the colon.
Where is the small intestine?
This is what we call consumed food when it is in the stomach.
What is chyme?
A substance flows from an area of high concentration to an area of low concentration.
What is diffusion?
What is passive transport?
A cell engages in this process to take in nutrients when passive and/or active transport won't work.
What is endocytosis?
This substance turns into pepsinogen to begin the digestion of proteins.
What is pepsin?
These break down fats into smaller pieces to prepare them for absorption.
What are bile salts?
This digestive process occurs in the small intestine. It results in carbs and other nutrients entering the bloodstream.
What is absorption?
These molecules are made of carbon, hydrogen, and oxygen. They are typically used a short term energy. They can be simple or complex.
What are carbohydrates?
This part of the cell membrane has two layers and cholesterol can be found inside it.
What is the phospholipid bi-layer?
The presence of proteins stimulate the secretion of this substance into the stomach to increase motility of the stomach contents.
What is gastrin?
In these molecules there is no more room for hydrogen bonds. The substances containing these molecules are solid at room temp.
What are saturated fats?
This molecule releases energy when one of its phosphate groups breaks off.
What is ATP?
