Answer:

The enzyme shows increased activity up to a certain temperature.

Explanation:

An enzyme is mostly a protein molecule/a biologist catalyst that speeds up the rate of a chemical reaction in a cell.

Enzymes lower the reaction's activation energy by attaching to the reactant molecule and positioning itself in a manner that readily facilitates chemical-bond breaking and forming process.

As the temperature increases, the rate of enzyme catalyzed reaction increases up to a maximum level (optimum temperature) and then decreases abruptly with any further temperature increase.This optimum temperature is 40°C for most animal enzymes.The abrupt decline in the rate of reaction after the optimum temperature is caused by the denaturing of enzymes by temperatures above 40°C.

As a molecule moves through the plasma membrane it passes through a hydrophobic layer of phospholipid tails then a hydrophilic l
Firdavs [7]

Answer:

"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>

Explanation:

Biological membranes are formed by two lipidic layers, proteins, and glucans.

Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.

Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.

Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.

in reference to carbon (IV) oxide, explain the concept of limiting factors in relation to photosynthesis
nekit [7.7K]

Answer:

As carbon dioxide concentrations increase, so too does the rate of photosynthesis until a certain point where the graph levels off. At lower carbon dioxide concentrations carbon dioxide is the limiting factor because an increase in carbon dioxide causes an increase in photosynthesis
