- - 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
