Answer:
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+
Explanation:
Pyruvate is converted to lactate by the enzyme lactate dehydrogenase under anaerobic condition.
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+ . This is because every glucose molecule that will be converted into pyruvate, two NADH molecules are produced and there is need for the NADH molecules to be oxidised back to NAD+ to ensure the continuity and maintenance of glycolysis.

Explanation:
Every substance produces light of different colors on the basis of level of energy that is possessed by the electrons of a substance.
<u>Explanation:</u>
Every substance has its level of energy. Depending upon that energy level the light of different colors id produced. There are electrons present in every substance that is made up of atoms and those atoms consist of electrons.
Whenever an atom is heated, the electrons present get excited and their energy level also increases but when their energy level comes down they emit energy in the form of light. The color of that light depends upon the level of energy of an electron. Each substance emits its color.
Answer:
Between steps 4 and 5, the mechanical energy of the turbine is converted to <u>electrical energy.</u>
Explanation:
A turbine can be described as rotating device which converts energy from fluid like water or energy from the wind into useful form of energy like electricity.
There are different types of turbines each made to generate energy from different sources.
To generate hydroelectricity, the water which is stored in a dam (potential energy) is released over a rotating turbine (mechanical energy) made of blades which converts it into electrical energy.
Answer:
True. The autonomic nervous system will attempt to maintain cardiac output by increasing the heart rate.
Explanation:
The autonomic nervous system is a system that controls some of the body functions. It acts unconsciously and regulates functions of the body such as the heart rate, respiratory rate, digestion, pupillary response, urination and sexual arousal.
In response to massive bleeding which reduced the volume of blood, stimuli from the baroreceptors( located within the blood vessels and heart) trigger the cardiovascular center of the brain to stimulate sympathetic responses, an action of the autonomic nervous system to increase cardiac output and vasoconstriction. This typically makes the heart rate to increase to approximately 180-200 contractions per minutes and thereby restoring cardiac output to normal level.
