Chapter 15 Flashcards
What are the phases of mitosis in order?
AH
Interphase, Prophase, Metaphase, Anaphase, Telophase
What is the fluid mosaic model?
AH
It describes the structure of the cell membrane, a mosaic of proteins and phospholipids.
What is facilitated diffusion?
AH
It is when carrier proteins bind to molecules and move them down a concentration gradient to an area of lower concentration.
What moves molecules against a concentration gradient, in a direction they would not go without input of energy?
AH
Active transport
In order what are the stages of respiration?
AH
Glycolysis, Krebs Cycle, Electron Transport Chain
The Cell Theory states…
KC
- All living things are made up of one or more cells
- All cells come from other cells
- Cells are the smallest unit of life
KC
The first to describe many types of living cells
KC
Anton Van Leeuwenhoek
KC
Between which two phases of the cell cycle does metaphase occur?
KC
Prophase and Anaphase
KC
What is Diffusion?
KC
It is the tendency of molecules to move from an area of high concentration to an area of low concentration
KC
The movement of water from an area of low solute concentration to an area of high solute concentration
KC
Osmosis
KC
What does the mitochondria do?
JC
breaks down organic molecules to obtain ATP
JC
What is the purpose of the cell membrane?
JC
It controls what travels into and out of the cell.
JC
What occurs during the G2 phase?
JC
Cells build machinery for cell division, and centrioles are copied.
JC
What is a substance that lowers activation energy?
JC
A catalyst
JC
What occurs during a light-dependent reaction?
JC
Water is split to produce oxygen, and sunlight energy is converted to ATP and NADPH energy.
