- actual set of environmental conditions (including presence/absence of other species) in which the species can establish a stable population
Which of the following processes takes place in the cytosol of a eukaryotic cell?-citric acid cycle-glycolysis-ATP production by ATP synthase-acetyl CoA formation-electron transport chain
a group of interacting species that occur together in the same place & time
Compact, complex animals have specialized internal ____ that provide a large surface area.
____ are usually composed of several types of tissues that together perform a specific task.
Respiration is called aerobic because ________.-it happens in the absence of oxygen-it requires carbon dioxide-it happens in mitochondria-it requires oxygen
The protective covering of the body is called the ____
In what organelle would you find acetyl CoA formation, the citric acid cycle, and the electron transport chain?-Golgi apparatus-lysosome-nucleus-mitochondrion-chloroplast
Most of the control mechanisms that maintain an internal steady state are based on ____ , in which a change in a variable triggers mechanisms that reverse that change.
Which statement describes the electron transport chain?-This process converts pyruvic acid to acetyl CoA.-This process produces some ATP and carbon dioxide in the mitochondrion.-This process splits glucose in half and produces 2 ATPs for each glucose.-This process joins 2 pyruvic acid molecules into a molecule of glucose.-This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.
entire niche that a species is potentially capable of using, based on physiological tolerance limits and resource needs
Monosaccharides __________, and polysaccharides __________.-are single monomer units; are made of many monosaccharides chained together-include cellulose; include glucose-cause diabetes; cause obesity-are made of proteins; are made of enzymes
____ are groups of several organs that work together to perform the functions of the body.
From what you learned in the video, how does blood glucose level change (or not change) in a non-diabetic human?-Blood glucose level decreases drastically if you skip a meal.-Blood glucose level stays exactly the same at all times.-Blood glucose level increases drastically after every meal.-Blood glucose level hovers within a narrow range.
Evaluate this statement: Cholesterol is a type of lipid, and thus all cholesterol lipids are bad for human health.-True, because high levels of cholesterol lead to obesity.-False, because cholesterol levels are not related to human health.-False, because some types cholesterol increase heart disease, but other types are necessary, especially in the plasma membrane.-True, because high levels of cholesterol lead to increased heart disease.
Which statement describes the citric acid cycle?-This process produces some ATP and carbon dioxide in the mitochondrion.-This process splits glucose in half and produces 2 ATPs for each glucose.-This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.-This process converts pyruvic acid to acetyl CoA.-This process joins 2 pyruvic acid molecules into a molecule of glucose.
____ is the regulation of internal conditions within a range that supports life's processes.
Which statement describes glycolysis?-This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.-This process converts pyruvic acid to acetyl CoA.-This process joins 2 pyruvic acid molecules into a molecule of glucose.-This process produces some ATP and carbon dioxide in the mitochondrion.-This process splits glucose in half and produces 2 ATPs for each glucose.
What kinds of molecules can be used as metabolic fuel to produce ATP?-amino acids, fatty acids, and CO2-sugars, amino acids, and fatty acids-sugars and fatty acids-water, sugars, and amino acids
Which energy-rich molecule produced by cellular respiration directly powers cell work?-Glucose-ATP-Water-O2
