A. Add the idea onto the present theory.

B. Ask the scientist to conduct further research.

Carbohydrate, Protein, and Fat Digestive Enzymes A key objective in this chapter is to identify the major enzymes in the digestion of carbohydrates, proteins, and fats as well as the organs that secrete them. This activity requires you to match the enzyme with the secreting organ. Drag the names of the enzymes to their respective bins, representing the appropriate secreting organ. Some organs secrete more than one enzyme. 1. pancreatic amylase2. pepsin3. salvary amylase4. gastnc lipase 5. pancreatic lipase6. trypsin 7. chymotrypsin8. carboxypeptidaseA. Salivary Glands B. Stomach C. Pancreas D. Small Intestine

Your airways are coated with a thin layer of liquid called ASL and a mucus gel layer, both which neutralize foreign particles to prevent infection. In people with
Cystic Fibrosis, a gene has an error, which causes the cells of the airways (lungs, etc) to have defective plasma membranes The ASL and mucus are much
thicker than usual near the defective cells, causing a lot of lung congestion because the defective cells allow too much salt into the cells Why would allowing too much salt into the cells create thicker ASL and mucus?

À. The increased salt in the cells makes the person thirsty, leading to thickened ASL and mucus in the lungs

B. The increased salt in the cells causes water from the airways to move into the cells by osmosis, thickening the ASL and mucus in the lungs.

C. The increased salt in the cells causes water from the cells to move into the airways, thickening the ASL and mucus in the lungs

D. The increased salt in the cells is absorbed by the cytoplasm of the cell causing water to leave the cells and enter the lungs,

Which statement best describes the relationship that exists among proteins, DNA, and cells?
A Proteins are made up of DNA, which determines the cells that are produced.
B Cells contain DNA, which controls the production of proteins.
C Proteins combine to produce cells, which produce DNA.
D DNA is made up of proteins, which tell a cell how to function.

what is the process of protein denaturation?

1) is usually temporary and reversible
2) changes the form of a protein, but not it’s function
3) is only possible in proteins with quaternary structure
4) is usually permanent and irreversible

Why are bacteria such as Rhizobium and cyanobacteria so important in the
nitrogen cycle?
A. They return nitrogen gas to air
B. They fix atmospheric nitrogen gas for the food chain
C. They decompose dead plants and animals
D. They build protein in plants

Which best describes thermal energy?
It is the difference between internal energies of two or more substances.
It is the sum of internal energies of two or more substances.
It is the portion of internal energy that can be transferred from one substance to another.
It is the portion of potential energy that can be transferred from one substance to another

Consider the impact of each substance on cellular respiration. Each substance has an influence at the cellular level, and has no effect on hunger. Assume that the substances have no other impact on the cell other than the one described. Substance’s Effect: Makes the lipid bilayer of the inner mitochondrial membrane highly permeable to (H+) protons. Does it cause weight gain or loss?

Which of the samples shown below are eukaryotic?

How are the molecules in photosynthesis and cellular respiration similar?

Varicella-zoster is the virus that causes chickenpox. The average incubation period is 14 to 16 days after exposure. A person usually experiences a mild fever and fatigue for 1 to 2 days before rashes appear all over the body. A person having had chickenpox as a child may have the virus lay inactive in the nerve cells for many years only to reactivate much later as an adult in the form of shingles, which results in a very painful rash. This information suggests that the reproductive cycle of the varicella virus is -
a)lytic for shingles because the virus causes rashes to appear on the skin.

b) lysogenic for chickenpox because the virus attacks the mucous membranes.

c) lysogenic because the virus is a varicella-zoster virus.

d) lytic for chickenpox because the symptoms appear soon after infection.

Which of the following best describes the formation of the bond shown in Figure 1 ?
А
An ionic bond is formed between a carbon atom of one amino acid and the nitrogen atom of the other amino acid,
B
An ionic bond is formed when the negative charge of an OH group is balanced by the positive charge of a hydrogen ion.
с
A covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of H2O
D
