input: OPTIONS:
- hydrophillic head , and adhesion tails
- hydrophillic head , and substrate tails
- hemophillic head, and substrate tails
- hydrophillic head , and hydrophobic tails Now, answer this question: Answer the following question given this paragraph: Figure 5.3 This phospholipid molecule is composed of a hydrophilic head and two hydrophobic tails. The hydrophilic head group consists of a phosphate-containing group attached to a glycerol molecule. The hydrophobic tails, each containing either a saturated or an unsaturated fatty acid, are long hydrocarbon chains. Q: What two things are a phospholipid molecules composed of? A:
A:
output: hydrophillic head , and hydrophobic tails

Answer the following question given this paragraph: Q: If citrate accumulates in mitochondria, some of it passes into where and inhibits phosphofructokinase? A:

- pores
- cytosol

Answer: cytosol

Q: Answer the following question given this paragraph: Energy is conserved in a closed system. That is, if you add up all the energy of an object(s) at one time it will equal all the energy of said object(s) at a later time. A closed system is a system where no energy is transferred in or out. The total energy of the universe is a constant (i. e. it does not change). The problems below do not consider the situation of energy transfer (called work). So friction and other sources where energy leaves the system are not present. Thus, one simply adds up all the potential energy and kinetic energy before and sets it equal to the addition of the total potential energy and kinetic energy after . Q: What happens to energy in a closed system? A:
Answer: is conserved

Problem:OPTIONS:
- catalysts
- oxides
- isotopes
- cations

Answer the following question given this paragraph: Some elements lose one or more electrons in forming ions. These ions are known as " cations " because they are positively charged and migrate toward the negative electrode ( cathode ) in an electrical field. Looking at the periodic table below, we know that the group 1 elements are all characterized by having one s electron in the outer orbit and group 2 elements have two s electrons in the outer orbit. These electrons are loosely attached to the atom and can easily be removed, leaving more protons in the atom that there are electrons, so the resulting ion has a positive charge. Cations can also be formed from electron loss to many of the transition elements. Q: What are electrons lost during the formation of ions called? A:
****
A: cations

Answer the following question given this paragraph: Prokaryotic cells are extremely small and have a variety of shapes. Most have flagella and a cell wall. They have several other cell structures as well. Their DNA exists as large and small loops. Some prokaryotes form biofilms, which are colonies of cells stuck to a surface. Q: What are colonies of cells stuck to a surface called? A:
OPTIONS:
- membranes
- cellular coating
- membranes
- biofilms
biofilms
