1.
active site: area where specific binding of substrate molecules occurs
2.
All life has the ability to...: absorb energy from its environment and convert it to another form
3.
anabolic reactions: biosynthesis reactions that build large molecules from snmall molecules
4.
ATP stands for: adenine triphosphate
5.
catabolic reactions: degredation reactions that break down large molecules into small molecules
6.
characteristics of life: ingestion, excretion, reproduction, response to stimuli, growth and development, structural organization
7.
chemical: synthesize or break up large molecules
8.
endothermic: heat energy absorbed
9.
enzymes: proteins that lower activation energy to speed reactions, don't get used up when catalyzing reactions
10.
enzymes are specific to...: substrates
11.
exothermic: heat energy released
12.
free energy: amount of energy available for work
13.
is reduction anabolic or catabolic?: anabolic
14.
Law of Conservation of Energy: energy cannot be created or destroyed. total is constant
15.
Law of Entropy: nature tends towards disorder
16.
mechanical: structure movement
17.
metabolism: all continuous chemical reactions in an organism
18.
organic molecules store...: chemical energy
19.
reduction: process is reduced, but gains electrons
20.
thermodynamics: conversion of energy between heat and other forms
21.
transport: moves nutrients
22.
two types of metabolism: anabolism and catabolism
23.
What does ATP do?: connects energy conversion reactions by breaking and building of PO4 bonds
24.
What does food go through?: esophagus
25.
What does the large intestine do?: removes water from food and absorbs it back into the body
26.
What happens to proteins when they are digested?: they are absorbed through the villi to produce ATP
27.
what is ATP called when it loses a phosphate?: ADP
28.
What is completely digested in the sm. intestine: carbohydrates and other foods
29.
What organ secrets juices to raise pH of sm. intestine?: pancreas
30.
What process causes food to move through the gastrointestinal tract?: peristalsis
31.
What protects the trachea?: epiglottis
32.
What sugar is in plants: glycogen
