How do hydrogen bonds in water affect its characteristics?

Hydrogen bonds, cause water to have a high enough surface tension that some organisms can actually move across it

The breakdown of a dye saccharide releases energy, which is stored as ATP. This is an example of a?

Exothermic reaction because it releases energy out

Which of the following metabolic compounds is composed of only carbon oxygen and hydrogen

Glycogen

When an animal takes in more energy than it actually uses over an extended time, the extra chemical energy is stored as what

Fat

Which of the following molecules is thought to have acted as the first enzyme in early life on earth

RNA

Which of the following are formed when the plasma membrane surrounds a particle outside the cell

Endocytotic vesicles

Which of the following plant organelles contain the pigment that gives green leaves their color

Chloroplasts

All, but which of the following processes are ways of moving salutes across a plasma membrane?

Passive transport, active transport, and facilitated diffusion are processes for moving solutes across a plasma membrane, but osmosis is not.

Prokaryote and eukaryotes are similar and having which of the following

Integral membrane proteins in the plasma membrane

Which of the following cell types has a peptidedoglycan cell wall

Bacteria. Remember if you give a dog Pepto-Bismol, they will have bacteria in their poopy.

Enzymes catalyze biochemical reactions by

Lowering the activation energy of the reaction

Which of the following is an example of a cofactor?

Remember, cofactors are in organic and mostly metal! Like zinc.

Cyanide is a poison that binds to the active sight of the enzyme, cytochrome C oxide days and prevent its activity.

Cyanide is an inhibitor. Remember an inhibitor prevents an activity from happening.

Which is not a characteristic of enzymes

Enzymes are always active on more than one kind of substrate. This is wrong. Remember that enzymes are substrate specific only.

MetaGenesis is referred to as

Alternation of generations

metagenesis contains both what?

Sexual phase and asexual phase in the lifecycle of a plant

What is the sexual phase called in moss and fern reproduction?

GAMETOPHYTE

The asexual phase in the reproduction or alteration of mosses and ferns

SPOROPHYTE

The ability for a plant to propel or shoot their seeds away from them, even up to several feet

Mechanical disposal

In organic nutrients and water enter plants through the root hair and travel to the what?

Xylem

Most of the plants water is lost through the stone matter by what process?

Transpiration

In order to maintain the remaining water that is necessary for the plant, what kind of cells control the still matter?

Guard cells

Water molecules cross the cell membranes of the root areas by what process

Osmosis

In organic nutrients are transported across the cell membranes of the root endodermis by what means?

Active transport

What is a single layer of cells that the water and nutrients must pass through by osmosis or active transport?

Endodermis

While water passes through by osmosis, mineral uptake is controlled by what?

Transport proteins

The xylem contained dead, water conducting cells called what and what?

Tracheids and vessels

Because water is cohesive, the water is pulled up by the wood as long as the water is transpiring

Xylem
