Biology Unit 2

Unit 2 Study Guide over Chapters 5-7

Ability of a system to perform work. Energy
What does energy allow to happen? The universe to exist.
What is the 1st form of energy? Potential
What is the 2nd form of energy? Kinetic
Potential energy is _______ and ___________. Solar/Chemical
Kinetic energy is ___________. Mechanical
Energy can't be created or destroyed but it can change from one form to another. 1st law of conservation of energy
Is energy recycled? (True or False) True
Energy can't be changed from one form to another without a loss of usable energy (heat). 2nd law of conservation of energy
Friction is not the reason why heat is generated? True or False False
In 2nd law of conservation of energy, food = ____________? Chemical
In 2nd law of conservation of energy, energy = ____________? Mechanical
3rd law of conservation of energy is? Entropy
Entropy means? disorganization
Energy in Entropy always goes down? True or false False
Any heat that is lost during energy conversion is Entropy? True or false True
The only way to maintain or bring order is to add energy to a system? True or false True
Explain how energy flows from the sun through an ecosystem. The sun shines down on plants or algae (photosynthesis) and converts it to sugar and oxygen (cellular respiration) and animals eat plants, organisms die and decompose.
Is the energy flow from the sun through a ecosystem 100% efficient? No
Where does the unused energy go? Recycled
Is the unused energy destroyed? No
Energy can't be created or destroyed. True or false True
Every process that occurs in the cell increases the total _____ of the universe. Entropy
Series of linked reactions thateed in an orderly, step-by-step manner. Metabolic pathway
Is the metabolic pathway all chemical or mechanical reactions? Chemical
Protein molecules used to speed up RNX. Enzyme
Potential energy is stored energy. True or False True
Kinetic energy is energy of demotion? False
Enzyme's are not recyclable or reused. True or false False
All enzymes consumed in reactions? True or false True
Enzymes are consumed in reactions? True or False False
Enzymes act as a ______ used to speed up processes. Catalyst
We can change the _________, _____________, and/or _________ but it will not change the way the enzyme works. Shape/temperature/PH
Enzymes are named generally after the ____________. Substrate
What do the names of enzymes typically end with? Ase
Enzyme undergoes slight shape change to accommodate substrate. Then the enzyme will go back to original form is called ___________ _________________. Feedback inhibition
Carbohydrates broken down and energy used to build ATP is called _______________ __________________. Cellular respiration
______________ uses sugar fro protist, fungi, animals, and bacteria. Metabolism
Question 20 goes here Question 20 goes here
Question 21 goes on yellow paper Question 21 goes on yellow paper
___________ takes place in the cytoplasm of a cell. Glycolysis
Glycolysis is the first step in cellular respiration of the ________ __________. Kreb's cycle
When glycolysis occurs, it breaks down glucose into _________ ________ in the cytoplasm. Pyruvic acids
In eukaryotes, the ___________ ___________ _________ takes place in the matrix of the mitochondria. Citric acid cycle (CAC)
The conversion of pyruvate to acetyl _____ takes place in the matrix of the mitochondria. CoA
In prokaryotes, these steps both take place in the __________. Cytoplasm
The _____________ ________________ _________________ for respiration occurs in the inner membrane layer of the mitochondria Electron transport chain
_____________ is a metabolic process that coverts sugar to acids, gasses or alcohol. Fermentation
It occurs in __________, _____________, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation Yeast/bacteria
When we work out, our muscles will tell us when they are heading to lactic acidosis-major problems that damage ________ and ______ in humans. Heart/muscles
The end products of fermentation are __________, __________ ________, and _________ ____________. Alcohol/carbon dioxide/lactic acid
The process is essential in the production of _______, fermented ______, and __________. Beer/milk/bread
To arrive at these end products, _________ are broken down in a process called glycolysis. Sugars
Indicate whether glycolysis are aerobic or anaerobic. Anaerobic
Indicate whether CAC are aerobic or anaerobic. Aerobic
Indicate whether ETC are aerobic or anaerobic. Anaerobic
Indicate whether fermentation are aerobic or anaerobic. Anaerobic
_______________ is what plants, algae and cyanobacteria do, living things use it. Photosynthesis
Photosynthesis makes the plants _______________. Producers
Producers feed themselves and all of the ____________ (most other living organisms on Earth) Consumers
