amylase is an example of an enzyme

In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins.Proteins are biological macromolecule and mostly composed of enzymes. Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators.

Select the correct statements about cellular respiration. (Check all that apply)

kogti [31]

Cellular respiration is the process by which glucose is broken down to carbon dioxide and water in the cell.

Cellular respiration refers to the process in which glucose is broken down to produce energy. The reaction of cellular respiration is; C6H12O6 -----> 6H20 + 6CO2. This process occurs in the mitochondria of the cell which is within the cytoplasm. In times of oxygen deficit, lactate or ethanol may be produced by the process.

The following statements are true about cellular respiration;

lactate may be produced

ethanol may be produced

the reactions happen in the cytoplasm

CO2 is produced

Which is the word equation for photosynthesis?

Evgen [1.6K]

Answer:

carbon dioxide + water → glucose + oxygen

Explanation:

Photosynthesis is the process that plants use to make food.

Think about what you need to grow a plant.

It needs water for sure.

Plants and humans both need air. Plants "breathe" in carbon dioxide, which is what we breathe out. (That's why people say to plant more trees, because they take in carbon dioxide.)

Plants use photosynthesis to make food. The food is called glucose, which is a form of sugar.

Plants "breathe" out oxygen, which is what we breathe in. (Remember trees give us oxygen.)

You might also see the equation as a formula:

CO₂ + H₂O → C₆H₁₂O₆ + O₂

Carbon (C) dioxide (O₂)

Water, or dihydrogen (H₂) monoxide (O)

glucose (C₆H₁₂O₆)

oxygen (O₂)

labwork [276]

Answer:

True

Explanation:

Epinephrine and norepinephrine are the hormones secreted by the adrenal medulla and are also called adrenaline and noradrenaline, respectively. During stress conditions, the hypothalamus stimulates the preganglionic neurons of sympathetic division.

These preganglionic neurons stimulate the chromaffin cells to secrete epinephrine and norepinephrine to prepare the body for fight or flight response. The increased level of epinephrine and norepinephrine hormones in the blood is called “surge of adrenaline”
