Body Systems
After a meal, what body system breaks down food into glucose?
Digestive System
Difference between unicellular and multicellular?
Unicellular (one cell) performs all functions to maintain life
All living things are made from...
Cells
What is the chemical reaction called when making energy?
cellular respiration
What is known as the powerhouse of the cell?
Mitocondria
What is the role of the circulatory system?
transferring molecules (glucose and AA) from the digestive system to the rest of the body
Word used to describe being unable to see with the naked eye
microscopic
What are ways to know that something is alive? (there are many, name one)
1. grows and develops
2. can reproduce
3. responds to surroundings
4. uses energy
oxygen and glucose
What type of cells would have the greatest number of mitochondria?
1. skin cells
2. blood cells
3. muscle cells
Muscle cells
What is the correct order of the circulatory system?
1. heart, arteries/veins, blood cells
2. blood cells, heart, arteries/veins
3. arteries/veins, heart, blood cells
Heart, arteries/veins, blood cells
What is the process called when you turn the food you eat into energy?
Metabolism
You take a sample of pond water. On day one you see microorganisms that are o.1 millimetes. Hours later you look again and it grew to 0.2 millimeters. Is it alive?
Yes, only living things can grow
Pablo is accused of blood doping. However he denies this accusation. What is an alternative way to increase the amount of oxygen in his cells.
High altitude training
What is starch and protein broken down into?
glucose and amino acids
What metabolic condition affects the airways and limits the amount of oxygen able to get into the cells?
Asthma
What part of the cell acts like the "skin" allowing molecules to go in and out of the cell?
cell membrane
What is an example of a unicellular (one cell) organism?
Bacteria
What are the waste products of cellular respiration?
Water and carbon dioxide
Regina has a condition that is making her feel tired all the time. She was recently in a car accident and she is experiencing nausea and belly pain. What kind of condition do you think she has? (One of the 4 metabolic conditions)
Injury to Pancreas
Sandy has a big soccer tournament tomorrow. She wants to make sure that she will have enough energy to well. What kind of foods should she eat before her game?
Foods high in starch and water
What is the "jelly" like substance that fills the cell. It holds all the cell parts in place and allows them to move around
cytoplasm
A student makes a model of a cell, to make the cell membrane she needs to decide wether to use a plastic bag or cloth bag. Which option would be a better choice and why?
Cloth bag because it allows some materials to pass through but not others. (glucose can enter cell, but starch cannot)
Wolf A was born at sea level where there are normal amounts of oxygen. Wolf B was born at 6000 feet above sea level where there is lower amounts of oxygen. After one year which wolf would have a greater mass? why?
Wolf A because the concentration of oxygen will be higher and cells receive more oxygen to perform cellular respiration, which will produce energy for growth.
Fix the statement, “Blood sugar (glucose) levels decrease in between meals because the excretory system removes glucose molecules from the body”.
The glucose levels decrease because glucose is used by body cells in cellular respiration in order to produce energy for growth and repair.
