Unit 1B Review Flashcards
This organelle is the control center of the cell and contains information for making proteins
nucleus

This type of transport does not require energy
passive

How will water move when a cell is placed in an isotonic solution?
in and out of the cell (but concentration does not change)
These organisms are able to make their own food
autotroph

These organisms must consume other organisms for food
heterotroph

How are photosynthesis and cellular respiration related?
the reactants of one are the products of the other

Glycolysis splits glucose into
2 molecules of pyruvic acid
How will water moves when a cell is placed in a hypertonic solution?
out of the cell
Give an example of a prokaryotic cell.
bacteria

List the 3 types of passive transport.

diffusion, facilitated diffusion, osmosis
What are the 3 parts of a ATP molecule?
adenine, ribose, 3 phosphate groups

In what organelle does cellular respiration occur?
mitochondrion

List 3 factors that increase the rate of photosynthesis.
adding water, increasing light intensity, having temperatures between 0 and 30 degrees Celsius
How many ATP are produced per molecule of glucose in cellular respiration?
36
What are the products of alcoholic fermentation?
alcohol and carbon dioxide
Where does glycolysis take place?
cytoplasm
What is the term for a cell that contains a nucleus?

eukaryotic
How is ADP different from ATP?
one less phosphate group
Which organelle releases energy from the nutrients taken into the cell?
mitochondrion
List 3 functions for the plasma membrane.

maintain homeostasis, boundary for the cell, allows materials to move in and out of the cell
Give 2 examples of active transport.
endocytosis (movement into the cell) and exocytosis (movement out of the cell)
How will water move when a cell is placed in a hypotonic solution?
into the cell

What gas is produced by the process of photosynthesis?
oxygen
Where do the light dependent reactions take place?

thylakoid membranes of the chloroplast
In which organelle does photosynthesis occur?
chloroplast
Which anaerobic process is used to produce bread and wine?
alcoholic fermentation

Where does the citric acid cycle take place?
matrix of mitochondrion

“Aerobic” means the process requires _____.
oxygen
Give an example of a eukaryotic cell.

The movement of molecules from high to low concentration is called _____.
diffusion
Diffusion with the help of transport proteins is called _____.
facilitated diffusion

Diffusion of water is _____.
osmosis

When we say something is moving down the concentration gradient, what does that mean?
It is moving from high to low concentration.

The movement of molecules from low to high concentration is called _____.
active transport
What happens when a phosphate group is removed from ATP?
ADP forms and energy is released

What happens when a phosphate group is added to ADP?
ATP forms and energy is stored

Where do the light independent reactions take place?
stroma of the chloroplast

What are the reactants of photosynthesis?
water and carbon dioxide

What are the reactants of cellular respiration?

The region outside the thylakoid membranes in a chloroplast is called the _____.
stroma

In this process, sugars are broken down to release water, carbon dioxide and energy
cellular respiration
List the steps of cellular respiration in order.
glycolysis, citric acid cycle, electron transport chain
When there is no oxygen, what process comes after glycolysis in muscle cells?
lactic acid fermentation
What is the difference between facilitated diffusion and active transport?
active transport requires energy
In this process, water and carbon dioxide and converted into sugars and oxygen
photosynthesis
What gas is produced by the process of cellular respiration?
carbon dioxide

hypertonic

What process caused the potato in the hypotonic solution to gain mass?
osmosis
