TEST BANK FOR HIGHER HUMAN BIOLOGY WITH 100% CORRECT ANSWERS

Catalyst - Answer A substance that speeds up the rate of a chemical reaction. Enzyme - Answer Protein that acts as a biological catalyst. Biochemical Pathways - Answer Organized sequence of chemical reactions. Metabolism - Answer The organic processes (in a cell or organism) that are necessary for life. Active Site - Answer The area of an enzyme where the catalysed reaction occurs. Substrate - Answer The specific substance that an enzyme acts upon. Denatured - Answe...

Active Transport - Answer Uses energy to move molecules against their concentration gradient. Adhering Junctions - Answer An intercellular junction that allows stretching of animal tissues. Carrier Protein - Answer Membrane protein which alters shape to move glucose or amino acids across. Cell - Answer Smallest Unit of life. Cell Membrane - Answer Surrounds the outside of cells & controls what enters and leaves. Cell Theory - Answer Idea that all living things ar...

organisms levels of organization - Answer atoms, molecules, cells, tissues, organs, organ systems, organisms, populations, community, ecosystem and biosphere. organisms - Answer take materials and energy from the environment reproduce grow and develop are homeostatic respond to stimuli have an evolutionary history and are adapted to a way of life Humans differ from other mammals by their,... - Answer highly developed brains completely upright stance creative language abili...

Chapter 1 - Answer -- The scientific study of life is called - Answer A. biology the science of ~biology~ is the study of living organisms and their environment (page 2) A complex individual that consists of organ systems is known as a - Answer C. Organism An individual; complex individuals contain organ systems (page 3) All of the ecosystems on the planet together are called the - Answer C. Biosphere All Earth's ecosystems collectively make up the ~biosphere~ (page 2)...

Tight junction - Answer junction which hold cells tightly together to prevent leaking; found in the urinary & digestive tract Adhesion junction - Answer junction where cells are not actually touching, but rather held together by intercellular filaments; found in the skin and heart muscle (allows flexibility) Gap junction - Answer connect cytoplasm of adjacent cells, only allow certain small molecules through; found in smooth muscle & heart (helps synchronize electricital activity) ...

Homeostasis - Answer State of body equilibrium characterized by a relatively constant and stable internal environment Enzymes - Answer - Facilitate biochemical reactions - are proteins -function as biological catalysts -speed up chemical reactions -are not altered or consumed by reaction -without enzymes, many biochemical reactions wouldn't proceed quickly enough to sustain life Lipids - Answer -Insoluble in water 3 important classes -Triglycerides - Energy storage...
