Answer:

The main product in the first step of cellular respiration is Pyruvate.

Explanation:

Cellular respiration invove 3 major steps the first step is glycolysis,the second step is TCA cycle and the last step is oxidative phosphorylation.

As Glycolysis is the first step of Aerobic respiration the main product of that step is Pyruvate which is the end product of Glycolysis.

Answer:

C. containing

egg albumen
protease
dilute hydrochloric acid

Explanation:

A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.

Enzymes speed up reaction rates by providing alternative pathways. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.

Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.

Spit lab hypothesis

Afina-wow [57]

Answer

The above statement is true.

A spit is formed through wave deposition

Explanation:

-A spit is an extended stretch of beach material that projects out to sea and is joined to the mainland at one end. Spits are also created by deposition.

-Spits are formed where the prevailing wind blows at an angle to the coastline, resulting in longshore drift. An example of a spit is Spurn Head, found along the Holderness coast in Humbersideore Brainlym
