Unit 1 Biology (glencoe)

sugar-phosphate backbone – The alternating chain of sugar and phosphate to which the DNA and RNA nitrogenous bases are attached.
Deoxyribonecleic acid (DNA) – Genetic material in all organisms; codes for protiens
Active Transport – Energy-requiring process that moves material across a cell membrane against a concentration difference (High–>Low).

Movement of materials through a cell membrane using cellular energy.

Needs cell to use it's own energy.

Analogous Structure – a structure that has a common function but different structure ex: butterfly wing/bat wing *evidence of evolution
* As the length of a cell increases, its volume increases (faster or slower) than its surface area 10.1 – faster
c4 Photosynthesis – can capture very low levels of cardon dioxide, needs extra energy in the for of ATP to function (ex. corn, sugar cane, sorghum)
sunlight – The source of energy that drives photosynthesis
Cell Wall in plants is made of – cellulose
cell theory – cell is the basic unit of life, performs function of all living things, and reproduce new cells from existing cells
chemiosmosis – The production of ATP in the electron transport chain as a result of H+ flowing though the protein ATP synthase from the inner mitochondrial space tot the matrix.
Which is the main organ of digestion and absorption?
elimination – The passing of undigested material out of the digestive compartment; the fourth and final stage of food processing in animals.
nervous tissues – It is made up of nerve cells that transmit and receive impulses, and is used in sensory input, muscle control, and mental activity.
62% of total energy of glucose that is not used to make ATP is… 9.2 – released as heat
Ribonucleic acid – is a molecule that stores information for protein synthesis and genetic coding.
exothermic reaction – absorb more energy than they release
Which is the mаin оrgаn оf digestiоn аnd absorption?
valence – The bonding capacity of a given atom; the number of covalent bands an atom can form usually equals the number of unpaired electrons in its outermost shell.
antiparallel – The opposite arrangement of the sugar-phosphate backbones in a DNA double helix.
