why is the digestion of starch to glucose necessary
Answer: The fundamental sugar unit for carbs is usually glucose. To address your question, starch digestion is required because enzymes and transport molecules require tiny, regular molecules to work with, and glucose is the foundation of most carbohydrate metabolism.
Explanation:
Answer:
The molecule of starch is too large and complex to enter a cell and therefore, it cannot be ingested directly. It is important to break down the bigger molecules of starch into smaller and simpler molecules of glucose so as to perform the process of glycolysis.
Explanation:
The process of glycolysis happens at a cellular level where glucose molecules are further broken down and utilized as energy to carry on various other cellular processes. The process of glycolysis happens in two stages namely:Energy requiring stage:Step 1: Glucose phosphorylation where a molecule of phosphorus is added to the glucose ring.Step 2: Energy releasing phase where the molecule of glucose-6-phosphate is converted to fructose-6-phosphate. Step 3: involves the phosphofructokinase reaction where fructose-6-phosphate is converted into fructose1,6-biphosphate.Step 4: involves an enzyme aldolase which converts the FBP into 23 carbon isomers.Step 5: involves the formation of glyceraldehyde-3-phosphate.Energy releasing stage: It breaks down glyceraldehyde-3-phosphate to pyruvate releasing 4 ATP and 2 NADP for cellular processes.For more information:

what by-product of anaerobic respiration makes this possible
Answer:
The end products of anaerobic respiration are Lactic acid or ethanol and ATP molecules. Anaerobic respiration takes place in the absence of oxygen and is seen in lower animals. During the process of Anaerobic Respiration in prokaryotes, there is a breakdown of glucose to produce energy for cellular activities.

Which of the following statements best describes a benefit of sexual reproduction?
It creates many offspring in a short amount of time.
A
B
It prevents mutations from being passed on to offspring.
С
It results in diversity of the species that enhances the probability of survival.
D
It ensures the offspring will receive only the best traits from each of the parents.
Among the listed options, we can conclude that option C which states that "It results in the diversity of the species that enhances the probability of survival." is correct.
Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is better adapted to a changing environment and promotes the faster evolution of a species.
The main benefit of sexual reproduction is that it allows for a greater diversity of the species which enhances the probability of survival. This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (the ability of a member of the species to choose a spouse with desirable traits) leads to offspring who over time are increasingly better adapted to life in the given environment, with specific traits tailored for survival.

why are they assuming the large molecules will stay on their own side of the membrane?
Answer:
What is osmosis? Why are they assuming the large molecules will stay on their own side of the membrane? The membrane is semipermeable, so the membrane only allows some molecules through and not others. In this case, it doesn't allow the large molecules through.
Explanation:
Hope It Helps
It is assumed that the large molecules will stay on their own side of the cell membrane because the membrane is semipermeable which only allows the passage of some molecules in and out of the membrane.
What is a Cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates and protects the inner environment of all cells from the outside environment. It is semi-permeable in nature.
The cell membrane consists of a lipid bilayer that is semi-permeable. The cell membrane regulates the transport of materials entering and exiting the cell.
The ability of a molecule to travel across a membrane depends on its concentration, charge, and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential.

A block of aluminum has a mass of 40.5 grams. If the density of aluminum is 2.7 g/mL, what is the
volume of this block?
Answer: 15 mL
Explanation:
Volume = Mass ÷ Density
= 40.5 g ÷ 2.7 g/mL
= 15 mL
∴ the volume of the block of aluminum is 15 mL.

Answer:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
ExplanatioEnzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without. However, the catalyst does not change the ∆G for the reaction.
Active sites and substrate specificity
To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates.
In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. In fact, whatever type of biological reaction you can think of, there is probably an enzyme to speed it up!
The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens
