Cellular Energy Study Guide

question

Photosynthesis
answer

The anabolic pathway in which light energy from the sun is converted to chemical energy for use by the cell
question

Cellular Respiration
answer

The catabolic pathway in which organic molecules are broken down to release energy for use by the cell
question

Mitochondria using glucose
answer

Breaks glucose apart and gets rid of the C from glucose by forming CO^2 and breathing it out. Uses CO^2 to mop up remaining H+ ions and electrons which forms water. Total of 36 ATP for each glucose.
question

Light Dependent Reaction
answer

Process in making glucose. Breaks water apart to run this. H- has electrons stripped from it and both electrons and the remaining H+ ions get used to run the process. O is not needed and released as a waste product.
question

Light Independent Reaction
answer

Making glucose step 2 after light dependent reaction. Takes CO^2 and makes glucose out of it. Energy to run this comes from light dependent reaction.
question

Cellular Respiration
answer

Goal is to make lots of ATP by releasing the energy stored in glucose. Happens in mitochondria. Uses carbon, hydrogen, and oxygen.
question

Calvin Cycle
answer

series of reactions during the light-independent phase of photosynthesis in which simple sugars are formed from carbon dioxide using ATP and hydrogen from the light-dependent reactions
question

Glycosis
answer

first step in releasing the energy of glucose in which a molecule of glucose is broken into two molecules of pyruvic acid
question

Krebs Cycle
answer

Second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
question

Glucose
answer

a monosaccharide sugar that has several forms
question

Water
answer

a fluid necessary for the life of most animals and plants
question

Sun Energy
answer

Major source of energy for all living things.
question

Electromagnetic Energy
answer

a form of energy that travels through space as waves
question

Chemical Energy
answer

that part of the energy in a substance that can be released by a chemical reaction
question

Oxygen
answer

a nonmetallic bivalent element that is normally a colorless odorless tasteless nonflammable diatomic gas
question

Carbon Dioxide
answer

a heavy odorless colorless gas formed during respiration and by the decomposition of organic substances
question

ATP
answer

(adenosine triphosphate) main energy source that cells use for most of their work
question

ADP
answer

adenosine diphosphate; molecule that ATP becomes when it gives up one of its three phosphate groups
question

Adenine
answer

nitrogen base found in DNA and RNA; pairs with thymine in DNA and with uracil in RNA
question

Ribose
answer

a pentose sugar important as a component of ribonucleic acid
question

Phosphate
answer

makes up the sides of the DNA ladder with deoxyribose
question

Lactic Acid
answer

waste product produced by Fermentation; causes muscles to be sore
question

Ethanol
answer

the intoxicating agent in fermented and distilled liquors
question

Fermentation
answer

Process by which cells release energy in the absence of oxygen., a chemical phenomenon in which an organic molecule splits into simpler substances
